Balanced Array Game

John is participating in the Balanced Array Game. In this game, he is given an array of integers. His objective is to guarantee a win by ensuring that the number of odd integers in the array is even. Formally, let \( \text{odd_count} \) denote the number of odd integers in the array. John wins if \( \text{odd_count} \equiv 0 \pmod{2} \); otherwise, he loses.

Your task is to determine whether John can guarantee a win. Output "YES" if the count of odd integers is even and "NO" otherwise.

inputFormat

The input is read from standard input (stdin) and consists of two lines:

• The first line contains an integer \( n \) representing the number of elements in the array.
• The second line contains \( n \) space-separated integers that represent the array elements.

outputFormat

Output to standard output (stdout) a single string: "YES" if the number of odd integers in the array is even, and "NO" otherwise.
