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.
Yet valid monad implementation must comply with three laws which Haskell type system isn't able to check.
Er, sorry, I didn't intend to mark my post as an Issue, seems it was done automatically by the feedback form.
(.+.) and (.*.) are somewhat clumsy, would it be more natural to make polynoms a Num instance?
Also I think the "show" method for polynoms should output "x" rather than "x^1", because that's more convenient and is shown in all examples except for one.
There should be some example tests, of course.
There is another issue posted 11 months ago. Seems nobody gives a care :(
Haskell's ability to easily manipulate infinite lists makes it language of the choice for this task :)
Same thing.
