9. Palindrome Number

Python

class Solution:
    def isPalindrome(self, x: int) -> bool:
        str_x = str(x)
        if str_x == str_x[::-1]:
            return True
        return False

Java

class Solution {
    public boolean isPalindrome(int x) {
        String str_x = Integer.toString(x);
        if ((new StringBuilder(str_x)).reverse().toString().equals(str_x)) {
            return true;
        }
        return false;
    }
}
