Palindrome Number

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?
