TODO 0007. Reverse Integer   medium

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 [-2^{31}, 2^{31} - 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:

  • -2^{31} <= x <= 2^{31} - 1

TODO Python

class Solution:
    def reverse(self, x: int) -> int:

TODO C++

class Solution {
public:
    int reverse(int x) {
        
    }
};
