[LeetCode/Python] Reverse Integer

문제 설명

Given a signed 32-bit integer x, return x with its digits reversed. If reversing x causes the value to go outside the signed 32-bit integer range [-231, 231 - 1], then return 0.

Assume the environment does not allow you to store 64-bit integers (signed or unsigned).

 

예시

 

제한

• -231 <= x <= 231 - 1

        else:
            answer = int(str(x)[::-1])
