Now input + returned and expected values are provided

it would completely spoil the kata though. the gist of the task is figuring out how to make the code compile

Added in Ruby.

All languages seem to have random tests now, resolving this.

List of prefixes added to the description.

Implicitly added the formula into the description, so now you don't necessarily need to go to Wikipedia for the formula.

Why did you mark it as a issue? It should be suggestion not issue

replaced with basic (not sure what base would mean here: a lame base sorting method...)

some languages do, some dont. re-raising here with a list of affected languages

Those are just some names I gave in the description to describe the requirement in words; they are not code fragments so language conventions don't apply.

I'm pretty sure this is not a good thing to do. This will make the description not lang-agnostic. This can cause a very messy description markdown just for handling formatting for different langs. Messy description is hard to maintain.

done

Added in latest fork

there are other issues about lack of random tests

I added ASCII art to the description to show the house of cards' structure
