Balance 编写的实现
Problem Description You are given a set of weight values and asked to measure something with a certain weight. Weight x is measurable with a set y of weight values if and only if you can do the following: Place one weight with value x on either the left or right side of the scale. Then place some combination of weights on the scale with values from the set y so that the left and right sides have the same total value. You may use each value in y zero or more times to achieve this. In order to reach the target, you choose a kind of weight randomly and try to measure with it. If you find it impossible, you choose an additional kind and try again until you can measure with the set of weights you have chosen. Now, please tell me the expect kinds of weight you have to choose. Input For each case, the first line is two integers n and m (1<=n<=15), which n represents the number of weights you have and m is the weight you have to measure. Followed by n positive integers ai (1<=i<=n), indicating the mass of each kind of weight. 0 < m,ai < 2^31. Output For each case, output -1 if you can't measure with all kinds of weight you have or the expect number of kinds you have to choose which rounded to 3 decimal places. Sample Input 1 2 3 3 3 1 2 3 3 5 2 3 4 Sample Output -1 1.333 2.333
Here’s a Product Which Will Make You Tensor
Problem Description Most people are familiar with how to multiply two matrices together. However, an alternate form of multiplication known as tensor multiplication exists as well, and works more like you would expect matrix multiplication should. Let A be a p × q matrix and B be an n × m matrix, where neither A nor B is a 1 × 1 matrix. Then the tensor product is a pn × qm matrix formed by replacing each element aij in A with the matrix (aij) · B. Two examples are shown below, which also demonstrate that, like normal matrix multiplication, tensor multiplication is non-commutative: Note that there is no restriction that the number of columns in the first matrix must equal the number of rows in the second, as there is with normal matrix multiplication. The object of this problem is to determine the number of ways (if any) a given matrix can be formed as a result of a tensor multiplication. Input The first line of input for a test case will contain two positive integers r and c indicating the number of rows and columns in the matrix. After this will follow r lines each containing c positive integers. The values of r and c will be ≤ 500, each entry in the matrix will be no greater than 65,536, and the last test case is followed by a line containing 0 0. Output For each test case, output the number of different ways the matrix could be the tensor product of two positive integer matrices, neither of which is a 1 × 1 matrix. Sample Input 6 6 1 1 1 2 2 2 1 1 1 2 2 2 1 1 2 2 2 4 3 3 3 4 4 4 3 3 3 4 4 4 3 3 6 4 4 8 2 2 3 6 4 9 2 4 15 18 30 36 20 24 40 48 0 0 Sample Output 1 0 4
Decompressing in a GIF 格式问题
Problem Description One well known method to compress image files is the Graphics Interchange Format (GIF) encoding, created by CompuServe in 1987. Here’s a simplified version applied to strings of alphabetic characters. Essential for this compression is a dictionary which assigns numeric encodings (we’ll use base 10 numbers for this problem) to different strings of characters. The dictionary is initialized with mappings for characters or substrings which may appear in the string. For example, if we expect to encounter all 26 letters of the alphabet, the dictionary will initially store the encodings (A, 00), (B, 01), (C, 02), . . . , (Z, 25). If we are compressing DNA data, the dictionary will initially store only 4 entries: (A, 0), (T, 1), (G, 2) and (C, 3). Note that the length of each initial encoding is the same for all entries (2 digits in the first example, and 1 digit in the second). The compression algorithm proceeds as follows: 1. Find the longest prefix of the uncompressed portion of the string which is in the dictionary, and replace it with its numeric encoding. 2. If the end of the string has not been reached, add a new mapping (s, n) to the dictionary, where s = the prefix just compressed plus the next character after it in the string, and n = the smallest number not yet used in the dictionary. For example, assume we started with the string ABABBAABB and a dictionary with just two entries, (A, 0) and (B, 1). The table below shows the steps in compressing the string. The final compressed string is 01234. There is only one other rule: the replacement strings used are always the size of the longest encoding in the dictionary at the time the replacement occurs. Thus, with the dictionary above, if the string to compress is long enough that an entry of the form (s, 10) is added to the dictionary, then from this point on all numerical replacement strings used in the compressed string must be expanded to 2 digits long (i.e., A will now be encoded as 00, B as 01, AB as 02, etc.); if an entry (s′, 100) is added to the dictionary, all replacements from this point forward will increase to 3 digits long, and so on. Thus, the longer string ABABBAABBAABAABAB will be encoded as 01234027301, not 0123402731. Try it! OK, now that you are experts at compressing, it’s time to relax and decompress! Input Each test case will consist of two lines. The first line will contain a string of digits to decompress. The second line will contain the initial dictionary used in the compression. This line will start with a positive integer n indicating the number of entries in the dictionary (1 ≤ n ≤ 100), followed by n alphabetic strings. The first of these will be paired with 0 in the dictionary (or 00 if n > 10), the second with 1, and so on. The last test case will be followed by a line containing a single 0. Output For each test case, output a single line containing the case number (using the format shown below) followed by the decompressed string. All input strings will have been legally compressed. Sample Input 01234 2 A B 01234027301 2 A B 02151120182729 26 A B C D E F G H I J K L M N O P Q R S T U V W X Y Z 21104 3 BA A C 01 2 JA VA 0 Sample Output Case 1: ABABBAABB Case 2: ABABBAABBAABAABAB Case 3: CPLUSPLUS Case 4: CAABAAA Case 5: JAVA
SanguoSHA 程序的问题
Problem Description SanguoSHA is a very popular game. The rules of SanguoSHA are too complex for me to describe it in English, so just let me simplify it a lot. ^ ^. In this custom game we have several rules shown below, and you should read carefully: Part I--Identifies: 1): There are at most 8 players while at least 4; 2): There are 4 roles: Lord, Minister, Rebel, and Traitor. 3): The goal of the Lord and Ministers is to kill all of the Rebels and the Traitor. 4): The goal of the Rebel is to kill the Lord. 5): The goal of the Traitor is to make himself alive until the game over. 6): There is only 1 Lord. 7): There is only 1 Traitor. 8): There will be at least 1 Rebel. 9): There will be at least 1 Minister. 10): Every player know the total remain number of Rebel and Minister. Part II--How to determine the game over and who wins: 1): If the Lord is alive, and there is neither alive Rebel nor Traitor, then the game over, and the Lord and Ministers win. 2): When the Lord is killed by someone, the game over, if there is no one but the Traitor alive, then the Traitor wins; otherwise, the Rebels win. Part III--How to play in this custom game: 1): At first, the roles of all players except for the Lord are hidden, they only know their own roles. That means players have to conjecture others' role by analysing their behavior. 2): In each round, all alive players play one by one. The player1 plays first, then player2... 3): In each player's turn, the player can choose one and only one player to attack. The probability of killing the chosen one is P. 4): When a player is killed, his role should be announced. Part IV--How to analysis player's behaviors: 1): The Lord is always be considered as Lord. 2): A player will be considered as Rebel when he attack the Lord. 3): A player will be considered as Rebel when he attack one which considered as Minister before all Rebels are eliminated. 4): A player will be considered as Minister when he attack one which considered as Rebel. 5): A player will be considered as Traitor when he have been considered as Minister and Rebel. 6): The players are not clever enough, they can't analysis other behaviors. Part V--The attack strategy of each role: Eliminated player couldn't do anything. No one will attack eliminated player or himself. For each strategy, all eligible player have equal probability of being attacked. The Rebel will choose one of the following strategies by order: 1)The Lord or Ministers if some players are considered as Minister. 2)The Lord or Traitor if a player is considered as Traitor. 3)The Lord. The Lord and Ministers will choose one of the following strategies by order: 1)The player which be considered as Rebel. 2)The player which be considered as Traitor. 3)If all rebel roles are eliminated, then attack anyone except Lord. 4)The player with unknown role. The Traitor will choose one of the following strategies by order: 1)The player which be considered as Minister if alive Minister number more than alive Rebel number. 2)The player which be considered as Rebel if alive Rebel number not less than alive Minister number. 3)Anyone expect the Lord. 4)The Lord. Such information will be given: 1): The number of players. 2): Each player's identify. 3): The probability of killing the chosen one. For each role, you should calculate the probability of winning within 10 round. Input The first line is a number T(1<=T<=30), represents the number of case. The next T blocks follow each indicates a case. Each case consists of three lines, the first line is an integer N(4<=N<=8), indicating the number of players. The second line contains N integers, player1,player2...playern, indicating the role of each player.(The first player will always be the Lord).(0, 1, 2, 3 indicating Lord, Minister, Rebel, and Traitor respectively.) Then the third line contains a real number P(0<P<1). Output For each case, output the number of case and the win probability of the 4 roles.Answers are rounded to 3 numbers after the decimal point.(as shown in the sample output) Sample Input 2 4 0 1 2 3 0.5 4 0 3 2 1 0.5 Sample Output Case 1: Lord and Minister:0.549 Rebel:0.334 Traitor:0.118 Case 2: Lord and Minister:0.501 Rebel:0.334 Traitor:0.166
It's not a Bug, It's a Feature! 具体实现
Problem Description It is a curious fact that consumers buying a new software product generally do not expect the software to be bug-free. Can you imagine buying a car whose steering wheel only turns to the right? Or a CD-player that plays only CDs with country music on them? Probably not. But for software systems it seems to be acceptable if they do not perform as they should do. In fact, many software companies have adopted the habit of sending out patches to fix bugs every few weeks after a new product is released (and even charging money for the patches). Tinyware Inc. is one of those companies. After releasing a new word processing software this summer, they have been producing patches ever since. Only this weekend they have realized a big problem with the patches they released. While all patches fix some bugs, they often rely on other bugs to be present to be installed. This happens because to fix one bug, the patches exploit the special behavior of the program due to another bug. More formally, the situation looks like this. Tinyware has found a total of n bugs B = {b1, b2, ..., bn} in their software. And they have released m patches p1, p2, ..., pm. To apply patch pi to the software, the bugs Bi+ in B have to be present in the software, and the bugs Bi- in B must be absent (of course Bi+ ∩ Bi- = Φ). The patch then fixes the bugs Fi- in B (if they have been present) and introduces the new bugs Fi+ in B (where, again, Fi+ ∩ Fi- = Φ). Tinyware's problem is a simple one. Given the original version of their software, which contains all the bugs in B, it is possible to apply a sequence of patches to the software which results in a bug- free version of the software? And if so, assuming that every patch takes a certain time to apply, how long does the fastest sequence take? Input The input contains several product descriptions. Each description starts with a line containing two integers n and m, the number of bugs and patches, respectively. These values satisfy 1 <= n <= 20 and 1 <= m <= 100. This is followed by m lines describing the m patches in order. Each line contains an integer, the time in seconds it takes to apply the patch, and two strings of n characters each. The first of these strings describes the bugs that have to be present or absent before the patch can be applied. The i-th position of that string is a ``+'' if bug bi has to be present, a ``-'' if bug bi has to be absent, and a `` 0'' if it doesn't matter whether the bug is present or not. The second string describes which bugs are fixed and introduced by the patch. The i-th position of that string is a ``+'' if bug bi is introduced by the patch, a ``-'' if bug bi is removed by the patch (if it was present), and a ``0'' if bug bi is not affected by the patch (if it was present before, it still is, if it wasn't, is still isn't). The input is terminated by a description starting with n = m = 0. This test case should not be processed. Output For each product description first output the number of the product. Then output whether there is a sequence of patches that removes all bugs from a product that has all n bugs. Note that in such a sequence a patch may be used multiple times. If there is such a sequence, output the time taken by the fastest sequence in the format shown in the sample output. If there is no such sequence, output ``Bugs cannot be fixed.''. Print a blank line after each test case. Sample Input 3 3 1 000 00- 1 00- 0-+ 2 0-- -++ 4 1 7 0-0+ ---- 0 0 Sample Output Product 1 Fastest sequence takes 8 seconds. Product 2 Bugs cannot be fixed.

linux expect脚本问题
1 #!/usr/bin/expect -f 2 spawn ssh root@192.168.1.121 3 expect "*password:" 4 send "test1234\r" 5 expect "*#" 6 send "mkdir ./ts\r" 7 send "file ts\r" 8 interact 实现登录到远端机器然后新建一个目录 查看这个目录的类型 为什么去掉第五行就不能正确执行了呢？而第六行和第七行就可以连续执行？ expect和send到底是怎么样的一个关系？ spawn mkdir ./test 这样无交互的指令是不是无法用expect编程 我试了下就执行了这句 尽管我指定了 expect “*\$“ 也没有继续执行接下去的send 语句 求教！
expect ftp 下载文件文件损坏，写法如下，
#!/bin/expect set timeout 30 set host 10.9.9.145 set login_name zzz set login_pwd zzz set localpath "/home/acc/songt/read" set remotepath "/home/acc/songt/write" spawn -noecho ftp -i \$host expect { timeout { exit 1 } "ame" } send "\$login_name\r" expect { timeout { exit 1 } "assword:" } send "\$login_pwd\r" expect { timeout { exit 1 } "assword:" { exit 1 } "ogin failed" { exit 1 } "ftp>" } send "passive\r" expect "ftp>" send "lcd \$localpath\r" expect "ftp>" send "cd \$remotepath\r" expect { timeout { exit 1 } "ftp>" } #LJ send "mget LJ*\r" expect { timeout { exit 1 } "ailed to open file" { exit 1 } "ad sequence of command" { exit 1 } "ftp>" } send "mdelete LJ*\r" expect { timeout {exit 1} "ailed to open file" {exit 1} "ad sequence of command" { exit 1 } "ftp>" } send "bye\r" exit 0
