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: key=lambda s: s[0] sorts by name, so the list is in reverse A to Z order.
The fix: sorted(students, key=lambda s: s[1], reverse=True)
Remember: the key decides what sorted() compares. Check which index holds what.
The pattern behind it: logic errors.
