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: or does not repeat the ==. The right side is just the text "Sunday", which counts as true.
The fix: return day in ("Saturday", "Sunday")
Remember: write the comparison on both sides of or, or use in with a tuple.
The pattern behind it: logic errors.
