Given an integer x, return true if x is a palindrome, and false otherwise.

  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 3:

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

  Constraints:

-2³¹ <= x <= 2³¹ - 1

  Follow up: Could you solve it without converting the integer to a string?
