Description
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.
Input
* Lines 2..N+1: Each line contains a single integer that is the milk output of one cow.
Output
Sample Input
5 2 4 1 3 5
Sample Output
3
Hint
Five cows with milk outputs of 1..5
OUTPUT DETAILS:
1 and 2 are below 3; 4 and 5 are above 3.
