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.
Get started now by creating a new collection.

I think that either tests should be written in a way that modifying input will not cause a problem or the statement should explicitely forbid input mutation.
Or is it forbidden generally for all problems here?
I had the same problem. If I move numbers generation inside a function it times out(system tests only), but outside a function works in 55ms.
