Let f(x) be the number of zeroes at the end of x!. (Recall that x! = 1 * 2 * 3 * ... * x, and by convention, 0! = 1.) For example, f(3) = 0 because 3! = 6 has no zeroes at the end, while f(11) = 2 because 11! = 39916800 has 2 zeroes at the end. Given…

题目如下: 解题思路:<编程之美>中有一个章节是不要被阶乘吓倒,里面讲述了“问题一:给定一个整数N,那么N的阶乘末尾有多少个0呢?例如N = 10, N! = 362800,N! 的末尾有两个0.” 这个问题的解法.本题就是在这个问题的基础上把输入和输出倒过来了.首先,对于输入参数K,我们可以知道输出结果的范围是[0,K*5],同时我们也可以知道,对于任意两个正整数i,j (i>j),i的阶乘一定是大于j的阶乘的,那么i的阶乘末尾0的数量也一定是大于或者j的阶乘末尾0的数量,既然是一个单…

Given an integer n, return the number of trailing zeroes in n!. Note: Your solution should be in logarithmic time complexity. Credits:Special thanks to @ts for adding this problem and creating all test cases. 这道题并没有什么难度,是让求一个数的阶乘末尾0的个数,也就是要找乘数中10的个数,…

Given an integer n, return the number of trailing zeroes in n!. Example 1: Input: 3 Output: 0 Explanation: 3! = 6, no trailing zero. Example 2: Input: 5 Output: 1 Explanation: 5! = 120, one trailing zero. Note: Your solution should be in logarithmic…

Given an array of n positive integers and a positive integer s, find the minimal length of a subarray of which the sum ≥ s. If there isn't one, return 0 instead. For example, given the array [2,3,1,2,4,3] and s = 7,the subarray [4,3] has the minimal…
