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.
I think there's a O(2n) or even O(n) solution, but the test cases are not really helpful to verify my ideas.
My pleasure, done.
Approved. With some reluctance set the difficulty to five, since this was the average rating. I think it's a 4kyu, but who am I to disrespect public opinion?
No excuses for mr dfhwze.
The only other strategy I know is the X-wing, so I suggest you start working. ;-)
I came here to get an answer on this as well.
Either I don't read the instructions well enough, or 5 is one of those hopeless nail lenghts.
I hope more people will solve this thing.
This deserves to be published.

I agree. Brilliant explanation of the problem. I wish I would have read the whole thing before diving in.
I'm not even going to pretend that I understand the top solution.
My opinion is that I like the idea.
I watched the video and it clicked.
Apologies for my semi-tantrum: I was a bit disappointed with myself for publishing the worst solution ever to the collinearity kata and took it out on Yushi.
@Yushi.py telling me I'm an idiot would do. Don't let my rank fool you: I like programming, but I'm not very good at it. I just solved half the easier Kata's available. ;-)
Surprised to see people here who seem to understand the description.
Big pass.
This solution makes me want to cry.
I saw An answer within minutes by looking at the tests.
Not the best answer, though.
