2443 - Sum of Number and Its Reverse.
Medium
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.
Example 1:
Input: num = 443
Output: true
Explanation: 172 + 271 = 443 so we return true.
Example 2:
Input: num = 63
Output: false
Explanation: 63 cannot be expressed as the sum of a non-negative integer and its reverse so we return false.
Example 3:
Input: num = 181
Output: true
Explanation: 140 + 041 = 181 so we return true. Note that when a number is reversed, there may be leading zeros.
Constraints:
0 <= num <= 105
