Rust translation has an incorrect reference solution. For example, if r = 6 and c = 11 then the correct expected value rounded down is -3. But Rust expects -2.

Also, Sample Tests do not compile.

The author of this kata states "There are no complicated formula that propagate many errors". I solved the kata with a rather complicated formula and it did propagate many errors, till I figure out when and where to do the notorious rounding.

Lua translation!

you should return the answer mod 1e9+7

There is an error here, when n=20 and k=20 the result should be 131282408400 but in the test case it says 282407483 (Python)

vaaaaaaaax! Don't I recognize you, whatt47? It seems like you leave a stream of havoc wherever you go.

Could you elaborate on the "expects us to hardcode wrong practices" part?

@daspreuße, man... Your katas are so badly broken. You are messy while writing instructions, your testing fails all over and specs for intended types are unclear, too. This particular kata expects us to hardcode wrong practices. I see no point doing these.

So many times I found you just copy things all over without any review or thorough revision what did you actually wrote.

From this very moment on I avoid your katas for good. It's not worth the time.

No, let's leave out 0^0 please :)
