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.
Ok, added this explicitly to the description. I would have preferred to improve the test messages, but they were locked already.
I had a problem figuring out the second part of description. Perhaps it would be more clear if it stated that second method should return results for each number in range between first & second number?
I think description could be improved - for example by saying that these 2 functions are supposed to produce identical output. It was a bit confusing at first.
