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.
Very interested kata! Thanks author for creation. Thats remaind me about some data structures in python. You nailed it!
Minor spelling mistake in description.
"The list of these words sorted withe its respespective ssw is [(888, 'question'),
(888, 'security'), (888, 'southern')], 'southern' should be chosen"
From the description "If the system does not have a unique solution (has infinitely many solutions or is unsolvable), return null (None in python)."
