Easy problem

Given an array of integers of length n,a₁, a₂... , a_n.

How many elements are there that, after removing this element, add up to an even number (tips : 0 is even)?

看不懂最后一句话可以划过下面的黑线，英语太蹩脚了*2！！！

请你找出共有多少个元素满足，在去掉该元素后，剩余元素的相加之和为一个偶数

The first line contains the integer n, representing the size of the array.

The second line contains n integers, representing a₁,a₂...a_n

(1 <= n <= 10⁵, 0 <= a_i <= 10⁹)

Output the number of elements that meet the condition.

10
8 6 10 1 3 9 3 1 7 4
