* Update all_combinations.py
The original implementation had limitations in handling edge cases and certain input parameters, leading to potential RecursionError.
* Update all_combinations.py
Added checks to handle cases where n or k are negative or where k is greater than n. In such scenarios, the function now returns an empty list, avoiding invalid recursive calls.
