2443. Sum of Number and Its Reverse Medium

1/**
2 * [2443] Sum of Number and Its Reverse
3 *
4 * Given a non-negative integer num, return true if num can be expressed as the sum of any non-negative integer and its reverse, or false otherwise.
5 *  
6 * <strong class="example">Example 1:
7 * 
8 * Input: num = 443
9 * Output: true
10 * Explanation: 172 + 271 = 443 so we return true.
11 * 
12 * <strong class="example">Example 2:
13 * 
14 * Input: num = 63
15 * Output: false
16 * Explanation: 63 cannot be expressed as the sum of a non-negative integer and its reverse so we return false.
17 * 
18 * <strong class="example">Example 3:
19 * 
20 * Input: num = 181
21 * Output: true
22 * Explanation: 140 + 041 = 181 so we return true. Note that when a number is reversed, there may be leading zeros.
23 * 
24 *  
25 * Constraints:
26 * 
27 * 	0 <= num <= 10^5
28 *
