Problem q

FJ is surveying his herd to find the most average cow. He wants to know how much milk this 'median' cow gives: half of the cows give as much or more than the median; half give as much or less.

Given an odd number of cows N (1 <= N < 10,000) and their milk output (1..1,000,000), find the median amount of milk given such that at least half the cows give the same amount of milk or more and at least half give the same or less.

这道题是最简单的一道，输入数组，排序，再把中间数输出 就行了。主要细节就是sort函数中排序规则的定义：bool cmp(int a,int b) return a>b;
