The description should say nil instead of None for ruby, but good job

Great use of defaultdict!

I would like the site to be faster. I also dislike that most of the time my code runs time out. I, and most people I think, would pay for a premium account (if those existed) if it ran better.

Can anyone explain how this works? I know what a partial function is (basically prefilling some of the args), but how is it used here?

No, stop

Very nice! Shame on codewars for mangling that.

This is really cool. Thanks for showing me this is possible with islice

This is the ugliest thing I've ever seen. I'm sorry.

I don't believe that's true, I just tested it out. Can you either say why you think so or give an example of an n that causes failure?

Hey since you added the unit test for [True, True, False, True...] etc, it's broken. It shouldn't succeed on anything besides [True, False], no repeats, just like the numbers.

Having no repeats made sense, you can't kill someone twice after all, and this thing you added broke that.

How can I debug this? How can I log what'd going on in the zmq_barista thread?

You can always just turn recursion limits off too (which also works here on codewars!)

Wow, great job! This is definitely not a 6kyu problem anymore. That's an awesome solution you have.

Try this with Fib(100), it's not computable (as far as I know) because of how this doubles the operations at each level of the recursion.
