[LeetCode]9、Palindrome Number

题目描述：

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

思路：检测是不是回文数。将给定的数翻转即可。与第七题的思路相同，网上给的解法是从头和尾同时遍历，比较是否相等，相等则删除继续比较，直到最中间一位。

public class Solution9 {
    public boolean isPalindrome(int x){
        int result = 0;
        int a = x;
        while(a>0){
            result = result*10+a%10;
            a/=10;
        }
        System.out.println(result);
        if(result == x){
            return true;
        }
        return false;
    }
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Solution9 solution9 = new Solution9();
        System.out.println(solution9.isPalindrome(-2147483648));
    }
