    This is my solution

    class Solution {
        bool isPalindrome(int x) {
            if(x<0) return false;
            string a = ""+to_string(x); bool bo = true;
            for(int i = 0; i< (a.length()+1)/2; ++i){
                if(a[i] != a[a.length() -1 -i]) {bo = false; break;}
            return bo;
