2443. Sum of Number and Its Reverse

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.

class Solution {
    long long reverse(int n) {
        int res = 0;
        while(n) {
            res = res * 10 + n % 10;
            n /= 10;
        }
        return res;
    }
public:
    bool sumOfNumberAndReverse(int num) {
        for(int i = 0; i <= num; i++) {
            if(i + reverse(i) == num) return true;
        }
        
        return false;
    }
