LeetCode - Palindrome Number

              用Java刷这道题没有太大意义。

 

public class Solution {
    public boolean isPalindrome(int x) {
        
        boolean ans = false;
        StringBuilder sb = new StringBuilder(x + "");
        String s = sb.reverse().toString();
        if(s.equals(sb.reverse().toString())) 
            ans = true;
        
        return ans;
        
    }
}
