LeetCode: Palindrome Number

一点小失误，基本一次过吧

 1 class Solution {

 2 public:

 3     bool isPalindrome(int x) {

 4         // Start typing your C/C++ solution below

 5         // DO NOT write int main() function

 6         int mul = 1;

 7         if (x < 0) return false;

 8         while (x/10 >= mul) mul *= 10;

 9         while (x) {

10             int left = x / mul;

11             int right = x % 10;

12             if (left != right) return false;

13             x -= left*mul;

14             x = (x - right) / 10;

15             mul /= 100;

16         }

17         return true;

18     }

19 };
