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.

While the emphasis is on the uniqueness of the features rather than their order, the final tests require that the features maintain their original order. It might be helpful to clarify: "Although order is not a factor when determining uniqueness, the final output should present the arrays in their original order."
Hey mgierczak, just a heads up: LAG with ORDER BY inside the window function usually avoids a second sort. No need for a CTE unless the sorts differ!

Rank 1 should probably be for the highest count.
However, when submitting solution with backwards ranking it was accepted by the test cases.
Great Kata; it was fun practising some recursion!
