Crash and Go(relians) 代码的写法
Problem Description The Gorelians are a warlike race that travel the universe conquering new worlds as a form of recreation. Generally, their space battles are fairly one-sided, but occasionally even the Gorelians get the worst of an encounter. During one such losing battle, the Gorelians’ space ship became so damaged that the Gorelians had to evacuate to the planet below. Because of the chaos (and because escape pods are not very accurate) the Gorelians were scattered across a large area of the planet (yet a small enough area that we can model the relevant planetary surface as planar, not spherical). Your job is to track their efforts to regroup. Fortunately, each escape pod was equipped with a locator that can tell the Gorelian his current coordinates on the planet, as well as with a radio that can be used to communicate with other Gorelians. Unfortunately, the range on the radios is fairly limited according to how much power one has. When a Gorelian lands on the alien planet, the first thing he does is check the radio to see if he can communicate with any other Gorelians. If he can, then he arranges a meeting point with them, and then they converge on that point. Once together, they are able to combine the power sources from their radios, which gives them a larger radio range. They then repeat the process—see who they can reach, arrange a meeting point, combine their radios—until they finally cannot contact any more Gorelians. Gorelian technology allows two-way communication as long as at least one of them has a radio with enough range to cover the distance between them. For example, suppose Alice has a radio with a range of 40 km, and Bob has a range of 30 km, but they are 45 km apart (Figure 1). Since neither has a radio with enough range to reach the other, they cannot talk. However, suppose they were only 35 km apart (Figure 2). Bob’s radio still does not have enough range to reach Alice, but that does not matter—they can still talk because Alice’s radio has enough range to reach Bob. If a Gorelian successfully contacts other Gorelians, they will meet at the point that is the average of all their locations. In the case of Alice and Bob, this would simply be the midpoint of A and B (Figure 3). Note that the Gorelians turn off their radios while traveling; they will not attempt to communicate with anyone else until they have all gathered at the meeting point. Once the Gorelians meet, they combine their radios to make a new radio with a larger range. In particular, the area covered by the new radio is equal to the sum of the areas covered by the old radio. In our example, Alice had a range of 40 km, so her radio covered an area of 1600π km. Bob’s radio covered an area of 900π km. So when they combine their radios they can cover 2500π km—meaning they have a range of 50 km. At this point they will try again to contact other Gorelians. This process continues until no more Gorelians can be contacted. As an example, suppose the following Gorelians have all landed and all have a radio range of 30 km: Alice (100, 100), Bob (130, 80), Cathy (80, 60), and Dave (120, 150). At this point, none of the Gorelians can contact anyone else (Figure 5). Now Eddy lands at position (90, 80) (Figure 6). Eddy can contact Alice and Cathy, so they arrange to meet at (90, 80), which is the average of their locations. Combining their radios gives them a range of √2700 ≈ 51.96 km (Figure 7). Now they check again with their new improved range and find that they can reach Bob. So they meet Bob at (110, 80) and combine their radios to get a new radio with a range of 60 (Figure 8). Unfortunately, this is not far enough to be able to reach Dave, so Dave remains isolated. Input The input will consist of one or more data sets. Each data set will begin with an integer N representing the number of Gorelians for this dataset (1 ≤ N ≤ 100). A value of N = 0 will signify the end of the input. Next will come N lines each containing three integers X, Y, and R representing the x- and y-coordinate where the Gorelian lands and the range of the radio (0 ≤ X ≤ 1000, 0 ≤ Y ≤ 1000, and 1 ≤ R ≤ 1000). Note that only the Gorelians' initial coordinates/range will be integral; after merging with other Gorelians they may no longer be integral. You should use double-precision arithmetic for all computations. The Gorelians land in the order in which they appear in the input file. When a Gorelian lands, he merges with any Gorelians he can contact, and the process keeps repeating until no further merges can be made. The next Gorelian does not land until all previous merges have been completed. Output The output will be one line per data set, reporting the number of independent groups of Gorelians that remain at the end of the process. Sample Input 5 100 100 30 130 80 30 80 60 30 120 150 30 90 80 30 6 100 100 50 145 125 10 60 140 15 160 145 20 130 135 25 80 80 30 0 Sample Output 2 3

Think I’ll Buy Me a Football Team 球队问题
Problem Description Falling Stocks. Bankrupted companies. Banks with no Cash. Seems like the best time to invest: ``Think I'll buy me a football team!" No seriously, I think I have the solution to at least the problem of cash in banks. Banks nowadays are all owing each other great amounts of money and no bank has enough cash to pay other banks' debts even though, on paper at least, they should have enough money to do so. Take for example the inter-bank loans shown in figure (a). The graph shows the amounts owed between four banks (A ...D). For example, A owes B 50M while, at the same time, B owes A 150M. (It is quite common for two banks to owe each other at the same time.) A total amount of 380M in cash is needed to settle all debts between the banks. In an attempt to decrease the need for cash, and after studying the example carefully, I concluded that there's a lot of cash being transferred unnecessarily. Take a look: 1. C owes D the same amount as D owes A, so we can say that C owes A an amount of 30M and get D out of the picture. 2. But since A already owes C 100M, we can say that A owes C an amount of 70M. 3. Similarly, B owes A 100M only, (since A already owes B 50M.) This reduces the above graph to the one shown in figure (b) which reduces the needed cash amount to 190M (A reduction of 200M, or 53%.) 4. I can still do better. Rather than B paying A 100M and A paying 70M to C, B can pay 70M (out of A's 100M) directly to C. This reduces the graph to the one shown in figure (c). Banks can settle all their debts with only 120M in cash. A total reduction of 260M or 68%. Amazing! I have data about inter-bank debts but I can't seem to be able to process it to obtain the minimum amount of cash needed to settle all the debts. Could you please write a program to do that? Input Your program will be tested on one or more test cases. Each test case is specified on N + 1 lines where N < 1, 000 is the number of banks and is specified on the first line. The remaining N lines specifies the inter-bank debts using an N×N adjacency matrix (with zero diagonal) specified in row-major order. The ith row specifies the amounts owed by the ith bank. Amounts are separated by one or more spaces. All amounts are less than 1000. The last line of the input file has a single 0. Output For each test case, print the result using the following format: k . B A where k is the test case number (starting at 1,) is a space character, B is the amount of cash needed before reduction and A is the amount of cash after reduction. Sample Input 4 0 50 100 0 150 0 20 0 0 0 0 30 30 0 0 0 0 Sample Output 1. 380 120

Snooker Referee 裁判的问题
Problem Description Snooker is a cue sport that is played on a large baize-covered table with pockets in each of the four corners and in the middle of each of the long side cushions. It is played using a cue and snooker balls: one white cue ball, 15 red balls worth one point each, and six balls of different colors: yellow (2 points), green (3), brown (4), blue (5), pink (6) and black (7). A player (or team) wins a frame (individual game) of snooker by scoring more points than the opponent(s), using the cue ball to pot the red and colored balls. In this problem, your job is the referee of snooker. You should score both players, ask the correct player to play next, as well as place some of the balls back to the table if necessary. The rules of snooker needed for this problem are following. (We ignore some fouls about incorrectly hitting the cue ball here. We assume that the cue ball is never snookered after a foul, so free ball will never occur. We also assume that both players will make their best attempts to hit the ball on, so you do not need to declare a miss when they do not hit the ball on first.) At the beginning of each frame the balls are set up by the referee as illustrated above. This will be followed by a break-off shot, the white cue ball can be placed anywhere inside the D (it is called in-hand, which also happens when the cue ball is potted). Players take turns in visiting the table. A break is the number of points scored by a player in one single visit to the table. A player's turn and break end when he fails to pot a ball, when he does something against the rules of the game, which is called a foul, or when a frame has ended. The ball or balls that can be hit first by the white are called the ball(s) "on" for that particular stroke. The ball(s) "on" differ from shot to shot: a red ball, if potted, must be followed by a color, and so on until a break ends; if a red is not potted, any red ball remains the ball "on". Only a ball or balls "on" may be potted legally by a player. If a ball not "on" is potted, this is a foul. The game of snooker generally consists of two phases. The first phase is the situation in which there are still red balls on the table. In the first phase, at the beginning of a player's turn, the balls "on" are all remaining red balls. The player must therefore attempt to first hit and pot one or more red balls. For every red ball potted, the player will receive 1 point. When a red has been potted, it will stay off the table and the player can continue his break. If no red has been potted or a foul has been made, the other player will come into play. In case one or more red balls have been potted, the player can continue his break. This time one of the six colors (yellow, green, brown, blue, pink and black) is the ball "on". Only one of these can be the ball "on" and the rules of the game state that a player must nominate his desired color to the referee, although it is often clear which ball the striker is playing and it is not necessary to nominate. When the nominated color is potted, the player will be awarded the correct number of points (yellow, 2; green, 3; brown, 4; blue, 5; pink, 6; black, 7). The color is then taken out of the pocket by the referee and placed on its original spot. Because only one of the colors is the ball "on", it is a foul to first hit multiple colors at the same time, or pot more than one color. If a player fails to pot a ball "on", it being a red or nominated color, the other player will come into play and the balls "on" are always the reds, as long as there are still reds on the table. The alternation between red balls and colors ends when all reds have been potted and a color is potted after the last red, or a failed attempt to do so is made. Then the second phase begins. All six colors have to be potted in ascending order of their points value (yellow, green, brown, blue, pink, black). Each becomes the ball "on" in that order. During this phase, when potted, the colors stay down and are not replaced on the table, unless a foul is made when potting the color, in which case the color is respotted. When only the black is left, the first score or foul ends the frame, and the player who has scored most points has won it. However, if the score is tied after that, the black is respotted, the players draw lots for choice of playing, the next player plays from in-hand, and the next score or foul ends the frame. When a foul is made during a shot, the player's turn is ended and he will receive no points for the foul shot. The other player will receive penalty points. Colors illegally potted are respotted (while reds are not), and if the cue ball is potted, the next player will play from in-hand. Fouls concerned in this problem are: 。failing to hit any other ball with the cue ball 。first hitting a ball "not-on" with the cue ball 。potting a ball "not-on" 。potting the white (in-off) Penalty points are at least 4 points and at most 7 points. The number of penalty points is the value of the ball "on", or any of the "foul" balls, whichever is highest. When more than one foul is made, the penalty is not the added total - only the most highly valued foul is counted. As players usually do not nominate a color explicitly when hitting the colors, please be tolerant and assume that he always nominate the ball with the lowest score when it cannot be deduced from the ball first hit (i.e. when the cue ball does not hit any ball or hit a red first). If a player commits a foul, and his opponent considers that the position left is unattractive, he may request that the offender play again from the resulting position. Input The input file contains multiple test cases. The first line of the input file is a single integer T (T ≤ 200), the number of test cases. For each test case (frame), the first line contains the names of the two players separated by a whitespace. The first player will take the break-off shot. Each name is made up of no more than 20 English letters, and the two names are different. After that, the input mainly consists of lines that describe a stroke each (with two exceptions stated later). A stroke is described by the color of the ball first hit by the cue ball (or "None" if the cue ball does not hit any ball), followed by zero or more colors of the balls potted, all separated by whitespaces. For example, a line "Red Red White Red" means the cue ball first hit a red ball, and 2 reds are potted as well as the cue ball itself; and a line "None" means the cue ball does not hit any ball thus no ball is potted. You can assume that all strokes are legal according to the balls remain on the table, and the cue ball will not hit two or more ball first simultaneously. A line "Play again" may appear if and only if the last stroke is a foul. It means the other player request that the offender play again from the resulting position. If a score or foul occurs when only the black is left, and the score is tied after that, a line with either player's name will follow. That means the player will play next as a result of the lot. The case end when the frame ends. There is a blank line before every test case. Output For each frame, print a line in the format "Frame K" first, where K is the index of this case starts from 1. Then use the output to indicate the referee's behaviors: 。When a frame begins, print a line in the format "PlayerName's turn, in-hand", where PlayerName is the name of the player who take the break-off shot. 。After each stroke, print a line "Foul!" first if it is a foul. Then print a line with current score in the format "ScoreA : ScoreB", where ScoreA is the score of the player who take the break-off shot, and ScoreB is the other player's score. After that, if the frame continue fairly (i.e. not only black is left before the stroke, or it is not a score or foul when only black is left), and some ball(s) should be respotted. Print a line with the word "Respot" following by the color(s) of the ball(s), all separated by whitespace. If more than one ball should be respotted, print their colors in ascending order of their values. Do not print anything if no ball needed to be respotted. At last (when the frame continue fairly and any necessary ball has been respotted), if the last player's break ends, print a line in the format "PlayerName's turn" to ask the other player to play next, where PlayerName is the next player's name. If the next player should play from in-hand, print "PlayerName's turn, in-hand" instead. 。After a foul, if the other player request that the offender play again, just print a line "PlayerName's turn" or "PlayerName's turn, in-hand" according to whether the cue ball is in-hand, where PlayerName is the offender's name. Note that the requester is actually requesting in his turn, after you asked him to play next. 。If a score or foul occurs when only the black is left, and the score is tied after that, print a line "Tie" after the score. Then print two lines "Respot Black" and "PlayerName's turn, in-hand" to respot the black and play from in-hand, where PlayerName is the next player's name (determined by the lot). 。When the frame ends, print a line "PlayerName wins" after the score, where PlayerName is the winner's name. Print a blank line between every two successive cases.

Cattle 的程序的编写
Description A group of more or less domesticated bovine animals (hereafter to be referred to as cattle) are to be loaded into railway freight cars of certain train. The train consists of K freight cars (and a locomotive, which is kind of irrelevant to this problem), which can be loaded with at most M animals each. A number from 1 to N is painted on each animal (all numbers are used and no two animals carries the same number so by easy induction on N one concludes that there are exactly N animals). The animals are patiently waiting to be loaded in a queue sorted by their numbers in ascending order (1 is the first to be loaded etc.). One freight car is loaded at a time by arbitrary number of animals (not exceeding M, of course) from the beginning of the queue and then locked so no subsequent load of animals to that freight car is possible. The process of loading is continued until all freight cars are locked. It is known that some clashing pairs of animals dislikes each other and if loaded in the same freight car then the stronger one will attempt to kill the other. It is also known that there are friendly pairs of animals where the stronger animal will always successfully protect the weaker one from attack of any other animal. If no alive friendly protecting animal is present, the attack of stronger animal of a clashing pair is always successfull. All attacks in a freight car starts when it is locked. The transportation lasts long enough for all attacks to finish. Write a program that will suggest the loading of animals to the freight cars so that the number of alive animals at the end of transportation will be as large as possible. Input The first line of the input contains three integers N, K, M; 1 <= N,K <= 1000, 1 <= M <= 20. The second line contains integer D – the number of clashing pairs among the animals. Each of the following D lines contains three mutually different integers A, B, C. The pair (A, B) represents a clashing pair, and the pair (C, B) represents a friendly pair of animals. The second animal in each pair is always the weaker one. A stronger animal of a clashing pair cannot be a weaker animal in any other pair (the first number A cannot occur as a second number anywhere). A weaker animal of a clashing pair has exactly one friendly protecting animal (the third number C is uniquely determined by the first two numbers A and B). Output The first and only line of the output consists of an integer – the maximal number of alive animals at the end of transportation. Sample Input 5 2 3 2 1 2 3 1 3 2 Sample Output 5

Snooker Referee 比赛裁判的算法
Problem Description Snooker is a cue sport that is played on a large baize-covered table with pockets in each of the four corners and in the middle of each of the long side cushions. It is played using a cue and snooker balls: one white cue ball, 15 red balls worth one point each, and six balls of different colors: yellow (2 points), green (3), brown (4), blue (5), pink (6) and black (7). A player (or team) wins a frame (individual game) of snooker by scoring more points than the opponent(s), using the cue ball to pot the red and colored balls. In this problem, your job is the referee of snooker. You should score both players, ask the correct player to play next, as well as place some of the balls back to the table if necessary. The rules of snooker needed for this problem are following. (We ignore some fouls about incorrectly hitting the cue ball here. We assume that the cue ball is never snookered after a foul, so free ball will never occur. We also assume that both players will make their best attempts to hit the ball on, so you do not need to declare a miss when they do not hit the ball on first.) At the beginning of each frame the balls are set up by the referee as illustrated above. This will be followed by a break-off shot, the white cue ball can be placed anywhere inside the D (it is called in-hand, which also happens when the cue ball is potted). Players take turns in visiting the table. A break is the number of points scored by a player in one single visit to the table. A player's turn and break end when he fails to pot a ball, when he does something against the rules of the game, which is called a foul, or when a frame has ended. The ball or balls that can be hit first by the white are called the ball(s) "on" for that particular stroke. The ball(s) "on" differ from shot to shot: a red ball, if potted, must be followed by a color, and so on until a break ends; if a red is not potted, any red ball remains the ball "on". Only a ball or balls "on" may be potted legally by a player. If a ball not "on" is potted, this is a foul. The game of snooker generally consists of two phases. The first phase is the situation in which there are still red balls on the table. In the first phase, at the beginning of a player's turn, the balls "on" are all remaining red balls. The player must therefore attempt to first hit and pot one or more red balls. For every red ball potted, the player will receive 1 point. When a red has been potted, it will stay off the table and the player can continue his break. If no red has been potted or a foul has been made, the other player will come into play. In case one or more red balls have been potted, the player can continue his break. This time one of the six colors (yellow, green, brown, blue, pink and black) is the ball "on". Only one of these can be the ball "on" and the rules of the game state that a player must nominate his desired color to the referee, although it is often clear which ball the striker is playing and it is not necessary to nominate. When the nominated color is potted, the player will be awarded the correct number of points (yellow, 2; green, 3; brown, 4; blue, 5; pink, 6; black, 7). The color is then taken out of the pocket by the referee and placed on its original spot. Because only one of the colors is the ball "on", it is a foul to first hit multiple colors at the same time, or pot more than one color. If a player fails to pot a ball "on", it being a red or nominated color, the other player will come into play and the balls "on" are always the reds, as long as there are still reds on the table. The alternation between red balls and colors ends when all reds have been potted and a color is potted after the last red, or a failed attempt to do so is made. Then the second phase begins. All six colors have to be potted in ascending order of their points value (yellow, green, brown, blue, pink, black). Each becomes the ball "on" in that order. During this phase, when potted, the colors stay down and are not replaced on the table, unless a foul is made when potting the color, in which case the color is respotted. When only the black is left, the first score or foul ends the frame, and the player who has scored most points has won it. However, if the score is tied after that, the black is respotted, the players draw lots for choice of playing, the next player plays from in-hand, and the next score or foul ends the frame. When a foul is made during a shot, the player's turn is ended and he will receive no points for the foul shot. The other player will receive penalty points. Colors illegally potted are respotted (while reds are not), and if the cue ball is potted, the next player will play from in-hand. Fouls concerned in this problem are: 。failing to hit any other ball with the cue ball 。first hitting a ball "not-on" with the cue ball 。potting a ball "not-on" 。potting the white (in-off) Penalty points are at least 4 points and at most 7 points. The number of penalty points is the value of the ball "on", or any of the "foul" balls, whichever is highest. When more than one foul is made, the penalty is not the added total - only the most highly valued foul is counted. As players usually do not nominate a color explicitly when hitting the colors, please be tolerant and assume that he always nominate the ball with the lowest score when it cannot be deduced from the ball first hit (i.e. when the cue ball does not hit any ball or hit a red first). If a player commits a foul, and his opponent considers that the position left is unattractive, he may request that the offender play again from the resulting position. Input The input file contains multiple test cases. The first line of the input file is a single integer T (T ≤ 200), the number of test cases. For each test case (frame), the first line contains the names of the two players separated by a whitespace. The first player will take the break-off shot. Each name is made up of no more than 20 English letters, and the two names are different. After that, the input mainly consists of lines that describe a stroke each (with two exceptions stated later). A stroke is described by the color of the ball first hit by the cue ball (or "None" if the cue ball does not hit any ball), followed by zero or more colors of the balls potted, all separated by whitespaces. For example, a line "Red Red White Red" means the cue ball first hit a red ball, and 2 reds are potted as well as the cue ball itself; and a line "None" means the cue ball does not hit any ball thus no ball is potted. You can assume that all strokes are legal according to the balls remain on the table, and the cue ball will not hit two or more ball first simultaneously. A line "Play again" may appear if and only if the last stroke is a foul. It means the other player request that the offender play again from the resulting position. If a score or foul occurs when only the black is left, and the score is tied after that, a line with either player's name will follow. That means the player will play next as a result of the lot. The case end when the frame ends. There is a blank line before every test case. Output For each frame, print a line in the format "Frame K" first, where K is the index of this case starts from 1. Then use the output to indicate the referee's behaviors: 。When a frame begins, print a line in the format "PlayerName's turn, in-hand", where PlayerName is the name of the player who take the break-off shot. 。After each stroke, print a line "Foul!" first if it is a foul. Then print a line with current score in the format "ScoreA : ScoreB", where ScoreA is the score of the player who take the break-off shot, and ScoreB is the other player's score. After that, if the frame continue fairly (i.e. not only black is left before the stroke, or it is not a score or foul when only black is left), and some ball(s) should be respotted. Print a line with the word "Respot" following by the color(s) of the ball(s), all separated by whitespace. If more than one ball should be respotted, print their colors in ascending order of their values. Do not print anything if no ball needed to be respotted. At last (when the frame continue fairly and any necessary ball has been respotted), if the last player's break ends, print a line in the format "PlayerName's turn" to ask the other player to play next, where PlayerName is the next player's name. If the next player should play from in-hand, print "PlayerName's turn, in-hand" instead. 。After a foul, if the other player request that the offender play again, just print a line "PlayerName's turn" or "PlayerName's turn, in-hand" according to whether the cue ball is in-hand, where PlayerName is the offender's name. Note that the requester is actually requesting in his turn, after you asked him to play next. 。If a score or foul occurs when only the black is left, and the score is tied after that, print a line "Tie" after the score. Then print two lines "Respot Black" and "PlayerName's turn, in-hand" to respot the black and play from in-hand, where PlayerName is the next player's name (determined by the lot). 。When the frame ends, print a line "PlayerName wins" after the score, where PlayerName is the winner's name. Print a blank line between every two successive cases.

Crash and Go(relians) 怎么实现的
Problem Description The Gorelians are a warlike race that travel the universe conquering new worlds as a form of recreation. Generally, their space battles are fairly one-sided, but occasionally even the Gorelians get the worst of an encounter. During one such losing battle, the Gorelians’ space ship became so damaged that the Gorelians had to evacuate to the planet below. Because of the chaos (and because escape pods are not very accurate) the Gorelians were scattered across a large area of the planet (yet a small enough area that we can model the relevant planetary surface as planar, not spherical). Your job is to track their efforts to regroup. Fortunately, each escape pod was equipped with a locator that can tell the Gorelian his current coordinates on the planet, as well as with a radio that can be used to communicate with other Gorelians. Unfortunately, the range on the radios is fairly limited according to how much power one has. When a Gorelian lands on the alien planet, the first thing he does is check the radio to see if he can communicate with any other Gorelians. If he can, then he arranges a meeting point with them, and then they converge on that point. Once together, they are able to combine the power sources from their radios, which gives them a larger radio range. They then repeat the process—see who they can reach, arrange a meeting point, combine their radios—until they finally cannot contact any more Gorelians. Gorelian technology allows two-way communication as long as at least one of them has a radio with enough range to cover the distance between them. For example, suppose Alice has a radio with a range of 40 km, and Bob has a range of 30 km, but they are 45 km apart (Figure 1). Since neither has a radio with enough range to reach the other, they cannot talk. However, suppose they were only 35 km apart (Figure 2). Bob’s radio still does not have enough range to reach Alice, but that does not matter—they can still talk because Alice’s radio has enough range to reach Bob. If a Gorelian successfully contacts other Gorelians, they will meet at the point that is the average of all their locations. In the case of Alice and Bob, this would simply be the midpoint of A and B (Figure 3). Note that the Gorelians turn off their radios while traveling; they will not attempt to communicate with anyone else until they have all gathered at the meeting point. Once the Gorelians meet, they combine their radios to make a new radio with a larger range. In particular, the area covered by the new radio is equal to the sum of the areas covered by the old radio. In our example, Alice had a range of 40 km, so her radio covered an area of 1600π km. Bob’s radio covered an area of 900π km. So when they combine their radios they can cover 2500π km—meaning they have a range of 50 km. At this point they will try again to contact other Gorelians. This process continues until no more Gorelians can be contacted. As an example, suppose the following Gorelians have all landed and all have a radio range of 30 km: Alice (100, 100), Bob (130, 80), Cathy (80, 60), and Dave (120, 150). At this point, none of the Gorelians can contact anyone else (Figure 5). Now Eddy lands at position (90, 80) (Figure 6). Eddy can contact Alice and Cathy, so they arrange to meet at (90, 80), which is the average of their locations. Combining their radios gives them a range of √2700 ≈ 51.96 km (Figure 7). Now they check again with their new improved range and find that they can reach Bob. So they meet Bob at (110, 80) and combine their radios to get a new radio with a range of 60 (Figure 8). Unfortunately, this is not far enough to be able to reach Dave, so Dave remains isolated. Input The input will consist of one or more data sets. Each data set will begin with an integer N representing the number of Gorelians for this dataset (1 ≤ N ≤ 100). A value of N = 0 will signify the end of the input. Next will come N lines each containing three integers X, Y, and R representing the x- and y-coordinate where the Gorelian lands and the range of the radio (0 ≤ X ≤ 1000, 0 ≤ Y ≤ 1000, and 1 ≤ R ≤ 1000). Note that only the Gorelians' initial coordinates/range will be integral; after merging with other Gorelians they may no longer be integral. You should use double-precision arithmetic for all computations. The Gorelians land in the order in which they appear in the input file. When a Gorelian lands, he merges with any Gorelians he can contact, and the process keeps repeating until no further merges can be made. The next Gorelian does not land until all previous merges have been completed. Output The output will be one line per data set, reporting the number of independent groups of Gorelians that remain at the end of the process. Sample Input 5 100 100 30 130 80 30 80 60 30 120 150 30 90 80 30 6 100 100 50 145 125 10 60 140 15 160 145 20 130 135 25 80 80 30 0 Sample Output 2 3
The Embarrassed Cryptographer 的程序的设计
Problem Description The young and very promising cryptographer Odd Even has implemented the security module of a large system with thousands of users, which is now in use in his company. The cryptographic keys are created from the product of two primes, and are believed to be secure because there is no known method for factoring such a product effectively. What Odd Even did not think of, was that both factors in a key should be large, not just their product. It is now possible that some of the users of the system have weak keys. In a desperate attempt not to be fired, Odd Even secretly goes through all the users keys, to check if they are strong enough. He uses his very poweful Atari, and is especially careful when checking his boss' key. Input The input consists of no more than 20 test cases. Each test case is a line with the integers 4 <= K <= 10100 and 2 <= L <= 106. K is the key itself, a product of two primes. L is the wanted minimum size of the factors in the key. The input set is terminated by a case where K = 0 and L = 0. Output For each number K, if one of its factors are strictly less than the required L, your program should output "BAD p", where p is the smallest factor in K. Otherwise, it should output "GOOD". Cases should be separated by a line-break. Sample Input 143 10 143 20 667 20 667 30 2573 30 2573 40 0 0 Sample Output GOOD BAD 11 GOOD BAD 23 GOOD BAD 31

Getting Driving License 程序的设计问题
Problem Description Have you got a driving license? Acquiring a driving license brings you a lot of benefits. You will regret for not passing the driving test or getting a driving license in your campus life. Why?College life is filled with much spare time,which you can use to improve yourself in many fields such as driving. During the time of taking driving lessons,Samuel met a lot of classmates whose time are occupied by their own work. The fact that they have little time to practice makes getting driving license increasingly difficult. Passing the driving test as soon as possible is suggested by these mates to the our college students who cannot drive. Know something about the driving test you can read the information in the background section,however,it is not related with this problem firmly. Surely,you can go to the problem section directly. Here is the background information on owning driving licenses in China mainland: To get a driving license successfully,you need to take about 4 tests at least. The first part is the theory exam which helps you know clearly about the transportation law in China mainland and other driving theory. The second is to test you whether you can drive a car forward out and backward in the garage at a very low speed(like aunts moving),move the car from one garage to another and drive out. The third section you need to pass is a little difficult than the second test. In this section,you should be able to drive to avoid the obstacles on the road,manage your car pass S formed way(your car's wheels can not be moved onto one of the tracks which leads your way out),after that you may have to make your car pass the 90 degree angle track,then pass the course equipped with very low bridge using one side of your car's wheel and so on. The forth part which is test the same day with the third test is called road driving test(but in the problem I designed the time between Part 3 and Part 4 is 1 month,just want to make the problem much easier).As you can refer from the word,it tests the ability of driving on the road,it is more practical and of more importance. If you seems not very lucky,you will have fifth section(The problem does not include the 5th part,you can ignore it in solving the problem).In this part you are required to driving at night which involves changing lights in addition . Teachers never taught how to drive at night unless your group is asked to take part in this test. But on the contrary,taught how to driving at night,of course,is necessary. Samuel had an experience of taking the fifth test to get the driving license in the summer of 2008. Tell you a secret,next time you meet a car comes from an opposite direction and the driver of that car does not change his front lights ,it probably means he/she needs special training on how to drive at night. To get a driving license,you should pass the 4 parts one by one. For example,if you failed in the section 2,you have to retry for a second time,third time...before you pass. After that you have the opportunity to enter Part 3. Here is the problem section you need read patiently: Some details you need to know: 1.The time between the two tests is generally about 1 month(If you fail in the test on your first attempt,you can try it a second time. Fail again the second time he have to go home and retry after 1 month). 2.And the time from you take the first test to your owning a license is within 2 years. 3.What's more,the passing score in Part 1 test is 90(that is to say if you get 89 or even lower at your first attempt,a second attempt is needed. You will pass until you get 90 or higher at the second time)and each of the rest parts the passing score is 80 at least. Input The input consists 2 major sections as usual, the test cases t,each of the test case involves an integer n and n scores one gets in the test and with n scores he passed the test or he failed to pass in the 2 years(of course here n>=4). All the number here are integers. Output Output is simple. Just output the time one needs to get a driving license (if time is within 2 years)using the format “It takes about m months to get a driving license.”If time is beyond 2 years please output the sentence “He failed to get a driving license within 2 years! ” Sample Input 3 5 89 90 95 84 80 7 80 90 70 80 75 85 80 7 80 90 70 70 80 85 85 Sample Output It takes about 3 months to get a driving license. It takes about 3 months to get a driving license. It takes about 4 months to get a driving license.

第一次数据库查询成功,第二次查询去失败了?
我编写一个Android应用,A页面拥有一个选项菜单,点击菜单中的选项,跳转到B页面,B页面接收从A页面传递的数据后,进行数据库查询,在本页面中显示相关内容。 B页面中通过动态添加View的方法,添加了按钮,点击按钮,可进行数据库查询,获取相关值在页面显示。 不过我不想每次返回A页面,选择选项菜单的另一项再进入B页面,于是我在B页面同样放置了选项菜单,让我点击B页面上的选项菜单时,直接在B页面上显示,不过却出现“java.lang.NullPointerException: Attempt to invoke virtual method 'android.database.Cursor android.database.sqlite.SQLiteDatabase.rawQuery(java.lang.String, java.lang.String[])' on a null object reference”的错误。 请问,要怎样做呢? 相关数据库查询的函数 public ArrayList<JapInfo> query_stylecolumn(String style_column, String alp_style) { String sql = String.format("SELECT hiragana,katakana,sound_path FROM Jap_Info AS j " + "LEFT JOIN Alp_style AS a " + "ON j.alpha_style_id = a.id " + "WHERE j.style_column = '%s' and a.style_name = '%s';",style_column,alp_style); ArrayList<JapInfo> japIf = new ArrayList<JapInfo>(); Cursor cursor = mDB.rawQuery(sql,null); while (cursor.moveToNext()){ JapInfo japIfo = new JapInfo(); japIfo.hiragana = cursor.getString(0); japIfo.katakana = cursor.getString(1); japIfo.sound_path = cursor.getString(2); japIf.add(japIfo); } cursor.close(); return japIf; }
Roll-call in Woop Woop High
Problem Description The new principal of Woop Woop High is not satisfied with her pupils performance.She introduced a new roll-call process to get a daily measure of the pupils' learning, which proceeds as follows:At the beginning of the daily roll-call period each pupil is handed a question, which they must attempt to answer, before proceeding to their classes. A pupil stops after the question is answered correctly. Each pupil is allowed up to five attempts to answer the question correctly. Pupils who answer correctly on the first attempt are marked present. Pupils who answer correctly after more than one attempt are encouraged to work at home. Pupils who fail to develop a correct answer within five attempts are given remedial classes after school. Pupils who do not give any answer are marked as abscent. Your task is to write a program that reads the pupils' assessments and generates performance reports for the principal to proceed with appropriate actions. Input The input starts with an integer K (1 <= K <= 100) indicating the number of classes. Each class starts with an integer N (1 <= N <= 50) indicating the number of pupils in the class. Each of the following N lines starts with a pupil's name followed by up-to five assessments of his/her answers. An assessment of 'yes' or 'y' indicates a correct answer and an assessment of 'n' or 'no' indicates a wrong answer. A pupil's name consists of a single string with no white spaces. Output The attendance report for each class consists of five lines. The first line consists of the sentence: "Roll-call: X", where X indicates the class number starting with the value of one. The second line consists of the sentence: ''Present: Y1 out of N'', where Y1 is the number of pupils who did not submit a wrong answer. The third line consists of the sentence: ''Needs to study at home: Y2 out of N'', where Y2 is the number of pupils who submitted a number of wrong answers before submitting the correct answer. The fourth line consists of the sentence: ''Needs remedial work after school: Y3 out of N'', where Y3 indicates the number of pupils whose submitted five wrong answers. The fifth line consists of the sentence: ''Absent: Y4 out of N'', where Y4 indicates the number of absent pupils. Sample Input 2 5 Doc n y sneezy n n no yes princecharming no n no no n goofy yes grumpy n y 5 evilemperor n y princesslia r2d2 no no y obeyonecanopy n no y darthvedar y Sample Output Roll-call: 1 Present: 1 out of 5 Needs to study at home: 3 out of 5 Needs remedial work after school: 1 out of 5 Absent: 0 out of 5 Roll-call: 2 Present: 1 out of 5 Needs to study at home: 3 out of 5 Needs remedial work after school: 0 out of 5 Absent: 1 out of 5
Carrying Out A Task
Problem Description During the process of the military exercise, there is a ship on the sea level .The ship will go to certain place to carry out a task. For every action, the ship has two ways to sail. They are normal sailing and accelerated sailing. The normal speed of the ship is certain, when the ship sails normally, it can only move 1 step to the adjacent normal sea level. The ship can also accelerate. There are 2 kinds of accelerated sailings, one is moving forward d steps (d <= 5) in a straight line, and it must move forward d steps exactly every time it accelerates, The d steps must be on the normal sea level, otherwise, it can not accelerate. The other is accelerating while getting through the undercurrent. There are a lot of undercurrents on the sea, and entering the undercurrent area needs to accelerate when the ship is 1 step to the undercurrent. However, the ship itself will be damaged more or less by the undercurrent, After entering the undercurrent, the speed of the ship will become normal immediately. Every time it accelerates, the ship has to consume a certain B energy, and when it starts up ,it carries certain B energy. While the ship is sailing on the sea, it needs to consume a certain A energy. One unit of distance will consume one unit of A energy, and when the ship starts up, it carries enough A energy. There are many reefs on the sea, and the ship can not get through. Now the ship is required to sail to the certain place, of course, to minimize the damage to the ship itself is a priority because the cost of ships is very expensive. The damage is, of course, the smaller, the better. At the same time, an attempt should be made to control the consumption of A energy to the smallest amount during the whole process because the cost of A energy is much more expensive than that of B energy, and you can use B energy which the ship carried when it started up as you wish. Now the question is to work out the minimal times of action from the departure point to the destination under the condition that to minimize the damage to the ship is a priority and then the consumption of A energy to the smallest degree. Input The input file contains several test cases, the first line contains an integer T, indicates the number of test cases. In each case the first line includes two integers n, m (5 <= n, m <= 20), which indicate the size of the sea level for military exercises, and n rows and m columns are the current state of the sea level ('S' indicates the ship's initial position, 'E' indicates the destination place, '#' indicates the reefs, '*' indicates the undercurrent , ' ' the normal sea level), followed a line with a number d in it, it indicates the distance of the first kind of acceleration, then another line includes two integers, indicate that the initial value of the B energy and the value of the B energy needed while accelerating every time. Output Output an integer to indicate the smallest times of action, and if can not reach the task place, then output "can not reach!" Sample Input 2 5 10 ########## #E # #*###### # #S # ########## 5 10 2 6 10 ########## #E # #*######*# #*######*# #S # ########## 5 3 2 Sample Output 8 can not reach!

2020年的1月,我辞掉了我的第一份工作
其实,这篇文章,我应该早点写的,毕竟现在已经2月份了。不过一些其它原因,或者是我的惰性、还有一些迷茫的念头,让自己迟迟没有试着写一点东西,记录下,或者说是总结下自己前3年的工作上的经历、学习的过程。 我自己知道的,在写自己的博客方面,我的文笔很一般,非技术类的文章不想去写;另外我又是一个还比较热衷于技术的人,而平常复杂一点的东西,如果想写文章写的清楚点,是需要足够...
