Description
Given a 32-bit signed integer, reverse digits of an integer.
Example 1:
1 | Input: 123 |
Example 2:
1 | Input: -123 |
Example 3:
1 | Input: 120 |
Note:
Assume we are dealing with an environment which could only hold integers within the 32-bit signed integer range. For the purpose of this problem, assume that your function returns 0 when the reversed integer overflows.
