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: a = b overwrites a. The old value is gone, so b = a just copies the same value back.
The fix: a, b = b, a
Remember: Python's a, b = b, a swaps safely in one line.
The pattern behind it: logic errors.
