Max loves to maximize elements. As such, he gives you an array \(a\) of length \(N\), and wants you to print the maximum product of any \(2\) elements in the array! Note that the two elements could both be the same element.
The first line will contain the integer \(N\ (1 \le N \le 100)\).
The next line will contain \(N\) integers, \(a_1, a_2, \ldots, a_N\ (|a_i| \le 10^9)\).
Output the maximum product of any two elements.
