-/**
- * 9. Palindrome Number
- * 
- * Determine whether an integer is a palindrome. An integer is a palindrome when it reads the same backward as forward.
-
-Example 1:
-
-Input: 121
-Output: true
-Example 2:
-
-Input: -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: 10
-Output: false
-Explanation: Reads 01 from right to left. Therefore it is not a palindrome.
-Follow up:
-
-Coud you solve it without converting the integer to a string?
