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.
You must return a new linked list (using the
Nodeconstructor). Currently you are returning an array of filtered nodes data. If you are not familiar with that, you should train on other easier katas using linked list and come back to this after, you'll see it's not hard actually.
