9 - Palindrome Number\. Easy Given an integer `x`, return `true` if `x` is palindrome integer. An integer is a **palindrome** when it reads the same backward as forward. For example, `121` is palindrome while `123` is not. **Example 1:** **Input:** x = 121 **Output:** true **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. **Example 4:** **Input:** x = -101 **Output:** false **Constraints:** * -231 <= x <= 231 - 1 **Follow up:** Could you solve it without converting the integer to a string?
