Given an array of positive integers, return how many values contain an even number of decimal digits.
Inspect each value and count only those with 2, 4, 6, or another even number of digits.
Inputnums = [12, 345, 2, 6, 7896]
Output2
Inputnums = [555, 901, 482, 1771]
Output1
1 ≤ nums.length ≤ 5001 ≤ nums[i] ≤ 100,000
