Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Yes, it is working. Because cata has bad tests :)
Okay, n is always positive, so it would never be 0.
But you can try something else, for example - 40585.
// 4! = 24
// 0! = 1
// 5! = 120
// 8! = 40320
// 5! = 120
Correct => 24 + 1 + 120 + 40320 + 120 = 40585
In your case => 24 + 0 + 120 + 40320 + 120 = 40584 (wrong...)
Wrong, try strong(0). It will return 'STRONG!!!!', but 0! = 1, so 0 != 1...
Also, the map is not necessary
