Count Even Numbers
Given an integer array nums, return the number of elements that are even.
An integer is even if it is divisible by 2. If nums is empty, return 0.
Examples
01 · Example 1
nums = [1,2,4,7,10] return = 3
The even numbers are 2, 4, and 10.
02 · Example 2
nums = [] return = 0
The array is empty.
03 · Example 3
nums = [-3,-2,0,5,8] return = 3
The even numbers are -2, 0, and 8.
Constraints
0 <= nums.length <= 1000-100000 <= nums[i] <= 100000
public int solution(int[] nums) {
// write your code here
}nums[1,2,4,7,10]
