The link is now correct.

I agree. My first tought was no roots -> empty poly. But i agree that the simplest case reduces to the unity constant polynomial.

I've corrected the kata. Thanks for your comments.

Description should be corrected following previous comments.

Thanks for the correction. The final test case was corrected but the example test not. This set of katas is simple I wanted to use them as introdutory exercises all in the same level.

Issues corrected. Thanks for your comments and verifications!

Thanks for your comments. I corrected the example, and clarified that the goal is indeed to train recursion on python.

I'm new to CW, and wanted to understand if it is possible to create a Kata where the validation is the printed output instead of the returned value of a function?

Base tests missing.
