Once again, you are bored because your teacher tells things that you already mastered years ago (this time he's explaining that (a+b)2=a2+2ab+b2). So you decide to waste your time with drawing modern art instead.Fortunately you have a piece of squared paper and you choose a rectangle of size n*m on the paper. Let's call this rectangle together with the lines it contains a grid. Starting at the lower left corner of the grid, you move your pencil to the upper right corner, taking care that it stays on the lines and moves only to the right or up. The result is shown on the left:Really a masterpiece, isn't it? Repeating the procedure one more time, you arrive with the picture shown on the right. Now you wonder: how many different works of art can you produce?InputThe input contains several testcases. Each is specified by two unsigned 32-bit integers n and m, denoting the size of the rectangle. As you can observe, the number of lines of the corresponding grid is one more in each dimension. Input is terminated by n=m=0.OutputFor each test case output on a line the number of different art works that can be generated using the procedure described above. That is, how many paths are there on a grid where each step of the path consists of moving one unit to the right orone unit up? You may safely assume that this number fits into a 32-bit unsigned integer.Sample Input5 41 10 0Sample Output1262#include<iostream>using namespace std;longlong f(long long m, long long n){if(n==0) return 1;else return f(m-1,n-1)*m/n;}int main(){longlongm,n;while(scanf("%I64d %I64d",&n,&m) &&n+m){printf("%I64d\n",f(m+n,min(m,n)));}return 0;}1、（并查集）若某个家族人员过于庞大，要判断两个是否是亲戚，确实还很不容易，现在给出某个亲戚关系图，求任意给出的两个人是否具有亲戚关系。

ACM题目、测试用例及参考答案汇编——一次ACM协会内部测试

ACM题目、测试用例及参考答案汇编——一次ACM协会内部测试第一题：梦境是虚幻吗？时间限制：3000ms 内存限制：65535KB 难度：★★描述《盗梦空间》是一部精彩的影片，在这部电影里，Cobb等人可以进入梦境之中，梦境里的时间会比现实中的时间过得快得多，这里假设现实中的3分钟，在梦里就是1小时。

然而，Cobb他们利用强效镇静剂，可以从第一层梦境进入第二层梦境，甚至进入三层，四层梦境，每层梦境都会产生同样的时间加速效果。

那么现在给你Cobb在各层梦境中经历的时间，你能算出现实世界过了多长时间吗？比如，Cobb先在第一层梦境待了1个小时，又在第二层梦境里待了1天，之后，返回第一层梦境之后立刻返回了现实。

那么在现实世界里，其实过了396秒（6.6分钟）输入第一行输入一个整数T（0<=T<=100)，表示测试数据的组数。

每组测试数据的第一行是一个数字M(3<=M<=100)随后的M行每行的开头是一个字符串，该字符串如果是"IN" 则Cobb向更深层的梦境出发了，如果是字符串"OUT"则表示Cobb从深层的梦回到了上一层。

如果是首字符串是"STAY"则表示Cobb在该层梦境中停留了一段时间，本行随后将是一个整数S表示在该层停留了S分钟（1<=S<=10000000)。

数据保证在现实世界中，时间过了整数秒。

输出对于每组测试数据，输出现实世界过的时间（以秒为单位）。

嘟嘟一次只能处理一项送水任务，等到当前的送水任务完成了，才能处理下一项。

在处理每项送水任务之前，路径上的水管都要进行一系列的准备操作，如清洗、消毒等等。

嘟嘟在控制中心一声令下，这些水管的准备操作同时开始，但由于各条管道的长度、内径不同，进行准备操作需要的时间可能不同。

供水公司总是希望嘟嘟能找到这样一条送水路径，路径上的所有管道全都准备就绪所需要的时间尽量短。

嘟嘟希望你能帮助他完成这样的一个选择路径的系统，以满足供水公司的要求。

另外，由于MY市的水管年代久远，一些水管会不时出现故障导致不能使用，你的程序必须考虑到这一点。

蓝桥杯ACM决赛经典试题及其详解

/*入门训练A+B问题问题描述输入A、B，输出A+B。

说明：在“问题描述”这部分，会给出试题的意思，以及所要求的目标。

输入格式输入的第一行包括两个整数，由空格分隔，分别表示A、B。

说明：“输入格式”是描述在测试你的程序时，所给的输入一定满足的格式。

做题时你应该假设所给的输入是一定满足输入格式的要求的，所以你不需要对输入的格式进行检查。

多余的格式检查可能会适得其反，使用你的程序错误。

在测试的时候，系统会自动将输入数据输入到你的程序中，你不能给任何提示。

比如，你在输入的时候提示“请输入A、B”之类的话是不需要的，这些多余的输出会使得你的程序被判定为错误。

输出格式输出一行，包括一个整数，表示A+B的值。

说明：“输出格式”是要求你的程序在输出结果的时候必须满足的格式。

在输出时，你的程序必须满足这个格式的要求，不能少任何内容，也不能多任何内容。

如果你的内容和输出格式要求的不一样，你的程序会被判断为错误，包括你输出了提示信息、中间调试信息、计时或者统计的信息等。

样例输入12 45说明：“样例输入”给出了一组满足“输入格式”要求的输入的例子。

这里给出的输入只是可能用来测试你的程序的一个输入，在测试的时候，还会有更多的输入用来测试你的程序。

样例输出57说明：“样例输出”给出了一组满足“输出格式”要求的输出的例子。

样例输出中的结果是和样例输入中的是对应的，因此，你可以使用样例的输入输出简单的检查你的程序。

要特别指出的是，能够通过样例输入输出的程序并不一定是正确的程序，在测试的时候，会用很多组数据进行测试，而不局限于样例数据。

有可能一个程序通过了样例数据，但测试的时候仍只能得0分，可能因为这个程序只在一些类似样例的特例中正确，而不具有通用性，再测试更多数据时会出现错误。

比如，对于本题，如果你写一个程序不管输入是什么都输入57，则样例数据是对的，但是测试其他数据，哪怕输入是1和2，这个程序也输出57，则对于其他数据这个程序都不正确。

A request list is made up with N positive numbers. The numbers denote at which floors the elevator will stop, in specified order. It costs 6 seconds to move the elevator up one floor, and 4 seconds to move down one floor. The elevator will stay for 5 seconds at each stop.For a given request list, you are to compute the total time spent to fulfill the requests on the list. The elevator is on the 0th floor at the beginning and does not have to return to the ground floor when the requests are fulfilled.InputThere are multiple test cases. Each case contains a positive integer N, followed by N positive numbers. All the numbers in the input are less than 100. A test case with N = 0 denotes the end of input.

The i-th room contains J[i] pounds of JavaBeans and requires F[i] pounds of cat food. FatMouse does not have to trade for all the JavaBeans in the room, instead, he may get J[i]* a% pounds of JavaBeans if he pays F[i]* a% pounds of cat food. Here a is a real number. Now he is assigning this homework to you: tell him the maximum amount of JavaBeans he can obtain.InputThe input consists of multiple test cases. Each test case begins with a line containing twonon-negative integers M and N. Then N lines follow, each contains two non-negative integers J[i] and F[i] respectively.
