This is my CPP solution.

class Solution {
public:
    bool isPalindrome(int x) {
        if(x < 0){
            return false;
        }
        long long int rev = 0;
        long long int y = x;
        while(y!=0){
            long long int pop = y%10;
            y/=10;
            rev = rev*10 + pop;
        }
        if(rev == x){
            return true;
        }
        return false;
    }
};
