And more importantly in this case, the appearance of your code is relatively meaningless compared to you failing to consider all cases of inputs. Honestly, the appearance of code is irrelevant. The goal is to absolutely accurately meet the requirements - the true, actual requirements. It may not be within scope to know all the information you need to know to cover all the cases, and that's certainly a problem. But the cleanliness of your code, assuming it functions correctly, is unimportant to the operation. (It certainly will be a maintenance cost, though.)
