题目描述: In a given integer array nums, there is always exactly one largest element. Find whether the largest element in the array is at least twice as much as every other number in the array. If it is, return the index of the largest element, otherwise

大家在参加ACM比赛或者参加c/c++实验技能竞赛的时候,如果遇到大量的输入和大量的输出时,调试起来很不方便.一来如果结果不正确的话,需要重复输入大量数据:二来如果大量输出的话,得仔细检查输出结果与正确答案是否一样.这两项任务有时让人很不舒服. 我们可以利用freopen()函数来重定向流,可以使调试起来更加简单方便. 一个简单的例子: #include <iostream> #include <cstdio> using namespace std; int main() { i
