The C# version is missing the e.g. example

Ruby translation submitted, if you want to approve it :)

Thanks to you for considering my opinion :)

You are right. I added more random and some edge test cases. Thanks for the feedback.

I would recommend to only start with katas with sample test cases; if the need arises, resubmit after you have added a few strategical print statements to get how your code is doing.

Should have many more test cases, including edge and random cases: let me know if you might appreciate a hand in that.

May I suggest many more tests, with edge test cases and more random situations?

Being somewhat new to programming, I can't even figure out what could be wrong with my solution when there aaren't any test cases shown.
Just felt the need to comment. Maybe somebody could write a post about what to do when your code fails..for example, how to go about figuring out what could be wrong.
I DO want to learn.

Wow, that was satisfying..I finally got it :)

Turns out, I had "mean" confused with "median"
