@ Duoas, thanks for the link, but I don't want to look at that thread quite yet. First I want to see if I am in the right direction with the following source code, which I have spent the last few hours writing. It's ugly and it doesn't seem to work well though. ...

C++ Code Editor: Previous:Write a C++ program to read seven numbers and sorts them in descending order. Next:Write a C++ program to replace all the lower-case letters of a given string with the corresponding capital letters. What is the difficulty level of this exercise?
leetcode-172-Factorial Trailing Zeroes 题目描述: Given an integern, return the number of trailing zeroes inn!. Note: Your solution should be in logarithmic time complexity. 要完成的函数: int trailingZeroes(int n) 说明: 1、这道题目要求输出n!中从后面数起有多少个连续的0。时间复杂度要求是O(...
[leetcode: Python]172. Factorial Trailing Zeroes 题目: Given an integer n, return the number of trailing zeroes in n!. Note: Your solution should be in logarithmic time complexity. 题意: 给定一个数N,得到N!,求这个阶乘的最后有几个0。 思考:实质是求这个N!里含有多少个5。 方法一:性能52...
