28. Reverse Integer

Write a function solve that reverses the digits of an integer. If the reversed integer overflows, return 0.

Example: Input: 123 Output: 321
Assume the input is a 32-bit signed integer, so the reversed integer must be within the range [-2^31, 2^31-1].

Make sure you return your solution, don't print!
