Hex Tile Equations 等式问题
Problem Description An amusing puzzle consists of a collection of hexagonal tiles packed together with each tile showing a digit or '=' or an arithmetic operation '+', '-', '*', or '/'. Consider continuous paths going through each tile exactly once, with each successive tile being an immediate neighbor of the previous tile. The object is to choose such a path so the sequence of characters on the tiles makes an acceptable equation, according to the restrictions listed below. A sequence is illustrated in each figure above. In Figure 1, if you follow the gray path from the top, the character sequence is"6/3=9-7". Similarly, in Figure 2, start from the bottom left 3 to get "3*21+10=73". There are a lot of potential paths through a moderate sized hex tile pattern. A puzzle player may get frustrated and want to see the answer. Your task is to automate the solution. The arrangement of hex tiles and choices of characters in each puzzle satisfy these rules: The hex pattern has an odd number of rows greater than 2. The odd numbered rows will all contain the same number of tiles. Even numbered rows will have one more hex tile than the odd numbered rows and these longer even numbered rows will stick out both to the left and the right of the odd numbered rows. 1.There is exactly one 2. '=' in the hex pattern. 3. There are no more than two '*' characters in the hex pattern. 4. There will be fewer than 14 total tiles in the hex pattern. 5.With the restrictions on allowed character sequences described below, there will be a unique acceptable solution in the hex pattern. To have an acceptable solution from the characters in some path, the expressions on each side of the equal sign must be in acceptable form and evaluate to the same numeric value. The following rules define acceptable form of the expressions on each side of the equal sign and the method of expression evaluation: 6.The operators '+', '-', '*', and '/' are only considered as binary operators, so no character sequences where '+' or '-' would be a unary operator are acceptable. For example "-2*3=-6" and "1 =5+-4" are not acceptable. 7.The usual precedence of operations is not used. Instead all operations have equal precedence and operations are carried out from left to right. For example "44-4/2=2+3*4" is acceptable and "14=2+3*4" is not acceptable. 8.If a division operation is included, the equation can only be acceptable if the division operation works out to an exact integer result. For example "10/5=12/6" and "7+3/5=3*4/6" are acceptable. "5/2*4=10" is not acceptable because the sides would only be equal with exact mathematical calculation including an intermediate fractional result. "5/2*4=8" is not acceptable because the sides of the equation would only be equal if division were done with truncation. 9.At most two digits together are acceptable. For example, " 9. 123+1 = 124" is not acceptable. 10.A character sequences with a '0' directly followed by another digit is not acceptable. For example,"3*05=15" is not acceptable. With the assumptions above, an acceptable expression will never involve an intermediate or final arithmetic result with magnitude over three million. Input The input will consist of one to fifteen data sets, followed by a line containing only 0. The first line of a dataset contains blank separated integers r c, where r is the number of rows in the hex pattern and c is the number of entries in the odd numbered rows. The next r lines contain the characters on the hex tiles, one row per line. All hex tile characters for a row are blank separated. The lines for odd numbered rows also start with a blank, to better simulate the way the hexagons fit together. Properties 1-5 apply. Output There is one line of output for each data set. It is the unique acceptable equation according to rules 6-10 above. The line includes no spaces. Sample Input 5 1 6 / 3 = 9 - 7 3 3 1 + 1 * 2 0 = 3 3 7 5 2 9 - * 2 = 3 4 + 8 3 4 / 0 Sample Output 6/3=9-7 3*21+10=73 8/4+3*9-2=43

Fruit Ninja Extreme 如何计算呢
Problem Description 　　Cut or not to cut, it is a question. 　　In Fruit Ninja, comprising three or more fruit in one cut gains extra bonuses. This kind of cuts are called bonus cuts. 　　Also, performing the bonus cuts in a short time are considered continual, iff. when all the bonus cuts are sorted, the time difference between every adjacent cuts is no more than a given period length of W. 　　As a fruit master, you have predicted the times of potential bonus cuts though the whole game. Now, your task is to determine how to cut the fruits in order to gain the most bonuses, namely, the largest number of continual bonus cuts. 　　Obviously, each fruit is allowed to cut at most once. i.e. After previous cut, a fruit will be regarded as invisible and won't be cut any more. 　　In addition, you must cut all the fruit altogether in one potential cut. i.e. If your potential cut contains 6 fruits, 2 of which have been cut previously, the 4 left fruits have to be cut altogether. Input 　　There are multiple test cases. 　　The first line contains an integer, the number of test cases. 　　In each test case, there are three integer in the first line: N(N<=30), the number of predicted cuts, M(M<=200), the number of fruits, W(W<=100), the time window. 　　N lines follows. 　　In each line, the first integer Ci(Ci<=10) indicates the number of fruits in the i-th cuts. 　　The second integer Ti(Ti<=2000) indicate the time of this cut. It is guaranteed that every time is unique among all the cuts. 　　Then follow Ci numbers, ranging from 0 to M-1, representing the identifier of each fruit. If two identifiers in different cuts are the same, it means they represent the same fruit. Output 　　For each test case, the first line contains one integer A, the largest number of continual bonus cuts. 　　In the second line, there are A integers, K1, K2, ..., K_A, ranging from 1 to N, indicating the (Ki)-th cuts are included in the answer. The integers are in ascending order and each separated by one space. &nbsp;If there are multiple best solutions, any one is accepted. Sample Input 1 4 10 4 3 1 1 2 3 4 3 3 4 6 5 3 7 7 8 9 3 5 9 5 4 Sample Output 3 1 2 3

Crazy Tank 坦克的算法
Problem Description Crazy Tank was a famous game about ten years ago. Every child liked it. Time flies, children grow up, but the memory of happy childhood will never go. Now you’re controlling the tank Laotu on a platform which is H meters above the ground. Laotu is so old that you can only choose a shoot angle(all the angle is available) before game start and then any adjusting is not allowed. You need to launch N cannonballs and you know that the i-th cannonball’s initial speed is Vi. On the right side of Laotu There is an enemy tank on the ground with coordination(L1, R1) and a friendly tank with coordination(L2, R2). A cannonball is considered hitting enemy tank if it lands on the ground between [L1,R1] (two ends are included). As the same reason, it will be considered hitting friendly tank if it lands between [L2, R2]. Laotu's horizontal coordination is 0. The goal of the game is to maximize the number of cannonballs which hit the enemy tank under the condition that no cannonball hits friendly tank. The g equals to 9.8. Input There are multiple test case. Each test case contains 3 lines. The first line contains an integer N(0≤N≤200), indicating the number of cannonballs to be launched. The second line contains 5 float number H(1≤H≤100000), L1, R1(0<L1<R1<100000) and L2, R2(0<L2<R2<100000). Indicating the height of the platform, the enemy tank coordinate and the friendly tank coordinate. Two tanks may overlap. The third line contains N float number. The i-th number indicates the initial speed of i-th cannonball. The input ends with N=0. Output For each test case, you should output an integer in a single line which indicates the max number of cannonballs hit the enemy tank under the condition that no cannonball hits friendly tank. Sample Input 2 10 10 15 30 35 10.0 20.0 2 10 35 40 2 30 10.0 20.0 0 Sample Output 1 0
Jenga 程序的编写
Problem Description In their spare time of training, Alice and Charles often play Jenga together. As they've played the game together so many times, they both know each others' performance as well as themselves'. Now with their success rate of each move provided, can you tell in what probability each of them will win? And of course, Alice and Charles, like other ACM-ICPC contestants such as you, are very clever. Jenga is a game of physical and mental skill. In Jenga, players take turns to remove a block from a tower and balance it on top, creating a taller and increasingly unstable structure as the game progresses. Jenga is played with 54 wooden blocks. Each block is three times as long as it is wide. To set up the game, the included loading tray is used to stack the initial tower which has 18 levels of three blocks placed adjacent to each other along their long side and perpendicular to the previous level (so, for example, if the blocks in the first level lie lengthwise north-south, the second level blocks will lie east-west). Once the tower is built, the players take turns to move. Moving in Jenga consists of taking one and only one block from any level (except those mentioned later) of the tower, and placing it on the topmost level in order to complete it. The blocks in the top level, and the level below it if the top level is not completed, cannot be removed. However, if the top level is completed, the blocks in the one below it can be removed. The removed block should be placed to make the top level as same as the other level (with no block removed). The move is successful if the tower does not fall. The game ends when the tower falls, or no block can be removed without making the tower fall (rarely happened). And the loser is the player who made the tower fall (i.e., whose turn it was when the tower fell), or who cannot make the move. Now let's consider each level of the tower, there're only four types of valid arrangement of wooden blocks, as illustrated above. At the beginning of the game, they're all of the type A (or rotated by 90 degrees). And by removing a block from type A, one will get either type B or type C (or the mirrored equivalent of type C). No block from type B can be removed without making the tower fall. From type C we can only remove a block and result in type D. Then no block can be removed further. So there are only three types of moves: (1) A -> B, (2) A -> C and (3) C -> D, in addition to adding the removed block to the top level. As Alice and Charles have played Jenga so many times, their success rate of each move is very stable and can be formulated as P = b - d*n, where b is the player's base success rate of this type of move, d is the decrease of success rate for each additional level, and n is the number of levels in the tower before this move. The incomplete top level also counts as one level. For example, if the game begins with 18 levels, and both players have the same performance with b = 2.8 and d = 0.1, then P will be 1.0 for the first turn, and become 0.9 between the 2nd and the 4th turns. If P does not lie in the range [0, 1], the nearest number in the range is indicated. (E.g. when a player cannot fail the first several moves, P will be more than 1 until n is a bit larger.) Input The input file contains multiple test cases. The first line of the input file is a single integer T (T ≤ 500), the number of test cases. Each test cases begins with a line of n0 (3 ≤ n0 ≤ 18), the number of levels in the tower when the game starts. (When n0 is not 18, the rule sare the same.) The second line contains 6 real numbers ba1, da1, ba2, da2, ba3, da3, indicating Alice's base success rates and the decreases of success rates for each of the three moves: (1) A -> B, (2) A -> C and (3) C -> D. The third line also contains 6 real numbers bc1, dc1, bc2, dc2, bc3, dc3, those of Charles. (0 ≤ b - d*n0 ≤ 2 and 0 < d ≤ 0.5 for all the 6 pairs of parameters. No real number will have more than 4 digits after the decimal point.) Output For each test case, print a line with Alice's winning probability, assume that she always moves first. Your answer should be rounded to the 4th digit after the decimal point. Sample Input 2 3 1.3 0.1 1.3 0.1 1.3 0.1 1.3 0.1 1.3 0.1 1.3 0.1 4 1.5 0.1 1.5 0.1 1.5 0.1 1.5 0.1 1.5 0.1 1.5 0.1 Sample Output 0.1810 0.8190
