Example 1:​

Input: x = 121
Output: true
Explanation: 121 reads as 121 from left to right and from right to left.

Example 2:​

Input: x = -121
Output: false
Explanation: From left to right, it reads -121. From right to left, it becomes 121-. Therefore it is not a palindrome.

Example 2:​

Input: x = 10
Output: false
Explanation: Reads 01 from right to left. Therefore it is not a palindrome.

Constraints:​

  • -231 <= x <= 231 - 1
