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.

I've approved it. Oops, sorry, first time mistake I suppose.
Yeah, I think that would be a good idea for js, since you need to be more explicit with numbers than in python. It can probably be mentioned in 'the goal' section.
fixed, split into positive/negative/zero
Yeah that is very similar. I'll unpublish this.
The only kata of that name I can find don't have any resemblance to this kata, so I don't think so.
I do not think there are any similar approved kata, or at least I couldn't find any, but that one is quite similar.
I would say that the specific restrictions on the inputs of this and the fact that they mean you have to solve it in a different way due to the much larger (up to 100 degree inputs vs up to 15) polynomials involved would make it distinct.
Oops, fixed that. I forgot that the fixed tests were not also in the sample tests.
