# -*- coding:utf-8 -*-
# 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.
