程序员笔试题

判断回文数：

Java 实现：

public class Solution {
    public boolean isPalindrome(int x) {
        Integer tmp = 0;
        while(x > tmp) {
            tmp = tmp * 10 + x % 10;
            if(tmp == 0) {
                return false;
            }
            x = x / 10;
        }
        return (x == tmp || x == tmp / 10);
    }
}
