The purpose of this repo is to provide exercises for practicing recursion which I think it does reasonably well. I focus on whether tests account for enforcing recursion and try not to get lost in all the possible edge cases that don't necessarily pertain to recursion itself. However, if other members of the community want to expand tests or other aspects of the repo, I welcome those additions.

Closing this issue, but feel free to contribute the suggested change if you find it valuable.
