[Solved] Code Coach in Swift: Super Sale, Test Case #6

Question

I can't pass the Test Case # 6. Does anyone solve this problem?

Answer 1

I solved this. I had just overlooked an error case when a user input is one item.

(In other words, the input of test case #6 is one item, so the answer is 0.)
