Reverse Integer
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], return 0.
Assume the environment does not allow you to store 64-bit integers, signed or unsigned.
Example 1
Input
x = 123Output
321Reversing the digits of 123 gives 321.
Example 2
Input
x = -123Output
-321The negative sign is preserved, and reversing the digits of 123 gives 321.
Constraints
- -2^31 <= x <= 2^31 - 1
