每日算法题 Reverse Integer

Hi, here's your problem today. This problem was recently asked by LinkedIn:

Write a function that reverses the digits a 32-bit signed integer, x. Assume that the environment can only store integers within the 32-bit signed integer range, [-2^31, 2^31 - 1]. The function returns 0 when the reversed integer overflows.

Example:
Input: 123
Output: 321

class Solution:

  def reverse(self, x):

    # Fill this in.



print(Solution().reverse(123))

# 321

print(Solution().reverse(2**31))

# 0
