Problem Statement

There are $N$ buildings aligned in a row. The $i$-th building from the left has a height of $H_i$.

Determine if there is a building taller than the first one from the left. If such a building exists, find the position of the leftmost such building from the left.

Constraints

• $1 \leq N \leq 100$
• $1 \leq H_i \leq 100$
• All input values are integers.

Input

The input is given from Standard Input in the following format:

$N$

$H_1$ $H_2$ $\ldots$ $H_N$

Output

If no building is taller than the first one from the left, print -1.

If such a building exists, print the position (index) of the leftmost such building from the left.
