1295\. Find Numbers with Even Number of Digits

Easy

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`
*   <code>1 <= nums[i] <= 10<sup>5</sup></code>
