1295. Find Numbers with Even Number of Digits
Given an array nums of integers, return how many of them contain an even number of digits.

Example 1:

Input: nums = [12,345,2,6,7896]
Output: 2
Explanation: 
12 contains 2 digits (even number of digits). 
345 contains 3 digits (odd number of digits). 
2 contains 1 digit (odd number of digits). 
6 contains 1 digit (odd number of digits). 
7896 contains 4 digits (even number of digits). 
Therefore only 12 and 7896 contain an even number of digits.

Constraints:

  • 1 <= nums.length <= 500
  • 1 <= nums[i] <= 10^5

Solution:

class Solution {
    public int findNumbers(int[] nums) {
        int count = 0;
        for(int e : nums){
            if( Integer.toString(e).length() % 2 == 0) count++;
        }
        return count;
    }
}
