1138 - Trailing Zeroes (III)   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 trail. Input Input sta…

题目链接:http://lightoj.com/volume_showproblem.php?problem=1138 题目就是给你一个数表示N!结果后面的0的个数,然后让你求出最小的N. 我们可以知道N!里5(包括5的倍数)的个数比2(包括2的倍数)的个数多,所以1对应5!,2对应10!... 而末尾0的个数与N成正比,1e8对应的N最大是400000015.我用二分查询N对应末尾0的个数,要是计算出来末尾0的个数比给你的数还大就L=mid+1,否则就R=mid. #include <iost…
