When solving code coach problems what does test case 3,4,5 check?

Answer 1

They are similar to cases 1 and 2, but they are hidden so challenges can't be solved with 5 ifs and hard-coded outputs

Answer 2

That's the tough part. You can try to look back at the challenge and see if you missed anything. If you can't figure it out, make a code snippet and make a question with it included.

Answer 3

My code failed in last 3 tests how can I know how to correct it?
