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 should specify in the description that the every other 0 should be counted as a negative.As it is,it might be interpreted that ALL the 0s after the first one should be counted as negative.Great kata otherwise!
This Kata doesn`t have tests for run examples,just for the final test.So this might be the issue.
Can you set a limit on the solve time when creating a kata?I manged to brute force it the stupid way with 2 loops.Or I got lucky in the random tests.

This would also return the titles where the same actor starred in 2 movies(film_actor primary key is actor_id,film_id). To fix it you need HAVING COUNT(DISTINCT film_id)=2.
Can somebody explain this one a little bit?
Ok,that`s one thing I have to say about this one:Hahahhahahahahahhahah!
