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.
The problem is somewhere else but I have no way of knowing where
How did I mess this? Thanks
In variant (3,4,5,6) (python, not sure tests are the same for different languages) when we use:
-> 3 and 4 go out (4 - their time)
-> 3 returns (3)
-> 5,6 go out (6)
-> 4 returns (4)
-> 3,4 go out (4)
The test gives answer 21, but it's possible for them to shorten time to 20, as shown above.
