这题好简单

public class Solution {    public boolean isPalindrome(int x) {        if (x < 0) {            return false;        }                List
    
      number = new ArrayList
     
      ();                while (x >= 10) {            number.add(x%10);            x = x / 10;        }        number.add(x);        int p = 0;        int q = number.size() - 1;        while (p < q) {            if (number.get(p) != number.get(q)) {                return false;            }            p++;            q--;        }        return true;    }}
