/**
 * 7. Reverse Integer

 Given a 32-bit signed integer, reverse digits of an integer.

 Example 1:
 Input: 123
 Output: 321

 Example 2:
 Input: -123
 Output: -321

 Example 3:
 Input: 120
 Output: 21

 Note:
 Assume we are dealing with an environment which could only store integers within the 32-bit signed integer range: [−231,  231 − 1].
 For the purpose of this problem, assume that your function returns 0 when the reversed integer overflows.
