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.
I haven't done this one yet. If I'm understanding correctly an example might look like this:
input: 48762839
all 5 digit strings: 48762 87628 76283 62839
the largest of the 5 digit sub strings is 87628
