Palindrome Number

c++

class Solution {public:    bool isPalindrome(int x) {        if (x < 0) return false;        string reverseStr;        string str;        int2string(x, reverseStr, str);        return reverseStr == str;    }private:    void int2string(int x, string &reverseStr, string &str) {        while (x > 0) {            reverseStr.push_back(x % 10);            x /= 10;        }        str = reverseStr;        reverse(str.begin(), str.end());    }};

python
