Statement

Given $n$ and $n$ integers $a_i$, find the minimum value among these $n$ integers.

Input

Input a positive integer $n$ on the first line, indicating the number of digits.

Input the second line with $n$ non-negative integers, representing $a_1, a_2, \dots, a_n$, separated by spaces.

The data guarantees that $n\le100$ and $0\le a_i \le 1000$.

Output

Output a non-negative integer representing the minimum value among these $n$ non-negative integers.
