Test a custom input to verify an edge case (e.g. empty lists, negative numbers, duplicates).
This bug belongs to the logic errors pattern
The wrong operator, an inverted condition, a formula the right way round but backwards.
What went wrong: In Python, calling max() on an empty iterable raises a ValueError when no default argument is provided.
The fix: Provide the default keyword argument: max(scores, default=0)
Remember: In Python, pass default=value to max() and min() to safely handle empty collections.
The pattern behind it: logic errors.
