Optimal Point on a Line

Description:

Input:

The first line contains integer n (1 ≤ n ≤ 3·10⁵) — the number of points on the line.

The second line contains n integers x_i ( - 10⁹ ≤ x_i ≤ 10⁹) — the coordinates of the given n points.

Output:

Print the only integer x — the position of the optimal point on the line. If there are several optimal points print the position of the leftmost one. It is guaranteed that the answer is always the integer.

Sample Input:
