   * Testcase Example:  '121'
   *
   * 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?
