LeetCode Records - Question 1295 Find Numbers with Even Number of Digits

Attempt 1: Use a helper function

class Solution {
    public int findNumbers(int[] nums) {
        int sum = 0;
        
        for (int num : nums) {
            if (isEvenNumberofDigits(num)) {
                sum++;
            }
        }

        return sum;
    }

    private boolean isEvenNumberofDigits(int num) {
        if (num <= 9) {
            return false;
        } else if (num <= 99) {
            return true;
        } else if (num <= 999) {
            return false;
        } else if (num <= 9999) {
            return true;
        } else if (num <= 99999) {
            return false;
        } else {
            return true;
        }
