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.
Thanks, I had the same question. The description of the kata really needs to be improved.
Yes, I agree. I didn't read all issues list before I posted.
There is an issue with the tests. For example, now we can successfully submit a solution that will accept
[[1, 2, 3, 4],
[3, 4, 1, 2],
[1, 2, 3, 4],
[3, 4, 1, 2]]
as valid data (although we have non-unique values in columns)
