9. Palindrome Number

Determine whether an integer is a palindrome. Do this without extra space.

没啥好说，判断一个数字是否为回文数字。

class Solution {public:    bool isPalindrome(int x) {        int newx = 0;        int xx = x;        while(xx > 0)        {            newx = newx * 10;            newx = newx + xx % 10;            xx = xx / 10;        }        if(newx == x)            return 1;        else            return 0;    }};
