Leetcode 7. Reverse Integer

class Solution:
    def reverse(self, x: int) -> int:
        ans = 0
        minus = False
        
        if x < 0: minus = True
        if 0 <= x < 10: return x
        
        temp = list(str(abs(x)))[::-1]
        ans = int(''.join(temp))
        if minus: ans *= -1

        return ans if -2**31 < ans < 2**31 else 0
