Problem Description大家常常感慨，要做好一件事情真的不容易，确实，失败比成功容易多了！做好“一件”事情尚且不易，若想永远成功而总从不失败，那更是难上加难了，就像花钱总是比挣钱容易的道理一样。话虽这样说，我还是要告诉大家，要想失败到一定程度也是不容易的。比如，我高中的时候，就有一个神奇的女生，在英语考试的时候，竟然把40个单项选择题全部做错了！大家都学过概率论，应该

You task is to find minimal natural number N, so that N! contains exactly Q zeroes on the trail in decimal notation. As you know N! = 1*2*...*N. For example, 5! = 120, 120 contains one zero on the tra

Problem Description要求(A/B)%9973，但由于A很大，我们只给出n(n=A%9973)(我们给定的A必能被B整除，且gcd(B,9973) = 1)。 Input数据的第一行是一个T，表示有T组数据。每组数据有两个数n(0  Output对应每组数据输出(A/B)%9973。 Sampl

阶乘因式分解（一）时间限制：3000 ms  |  内存限制：65535 KB难度：2描述给定两个数m,n,其中m是一个素数。将n（0输入第一行是一个整数s（0随后的s行, 每行有两个整数n，m。输出输出m的个数。样例输入2100 516 2样例输出2415若先求n的阶乘，则很有
