## 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!

```python
def solve(n):
    pass
```
