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).
Example 1:
Input: x = 123
Output: 321
Example 2:
Input: x = -123
Output: -321
Example 3:
Input: x = 120
Output: 21
Constraints:
-231 <= x <= 231 - 1
My Answer
class Solution:
def reverse(self, x: int) -> int:
negative = 1 if abs(x) == x else -1
result = negative * int(str(abs(x))[::-1])
if abs(result) > 2**31 or result< -2**31-1:
return 0
