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: "".split(",") gives [""], which has length 1.
The fix: if text == "": return 0 before splitting.
Remember: test every parser with empty input first.
The pattern behind it: logic errors.
