7. Reverse Integer

LeetCode - 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.
