Given an integer x, return true if x is palindrome integer.

\n\n

An integer is a palindrome when it reads the same backward as forward.

\n\n\n\n

 

\n

Example 1:

\n\n
\nInput: x = 121\nOutput: true\nExplanation: 121 reads as 121 from left to right and from right to left.\n
\n\n

Example 2:

\n\n
\nInput: x = -121\nOutput: false\nExplanation: From left to right, it reads -121. From right to left, it becomes 121-. Therefore it is not a palindrome.\n
\n\n

Example 3:

\n\n
\nInput: x = 10\nOutput: false\nExplanation: Reads 01 from right to left. Therefore it is not a palindrome.\n
