    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.
