+/**
+ * 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.
+ *
+ * Example 2:
+ * Input: nums = [555,901,482,1771]
+ * Output: 1
+ * Explanation:
+ * Only 1771 contains an even number of digits.
+ *
+ * Constraints:
+ * 1 <= nums.length <= 500
+ * 1 <= nums[i] <= 10^5
+ * */
