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.
Are you sure it's O(1)?
Doesn't sound possible unless you've harcoded all the answers
Nice, didn't know the CodeWars environment inclues Megaparsec

Thank you for an advice. Really it is better to use meaningful names, and to use exceptions :)
I have been thinking about this. Even I think that
type ErrorString = StringEither ErrorString Stringis more idiomatic.But on other hand kata description says that function must be called get_reversed_color and exception should be raised.
Do you suggest to not take a look at this? or change kata description?
