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
