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?
