Some interesting math, recreationally speaking.

Well basically you get a message saying your solution is time-wise innefficient. You should provide a solution with code for production.

What did you learn?

Java translation

It's always great to learn something new finding direct solutions to these sorts of problems.

Merged.

C: in the random tests, the user function is tested against itself

fork fixing it, also clearing a warning and moving the testing code out of preloaded

After a quick scan, I only found C, C++, coffeescript and JS to have some kind of restrictions. The way I see it, either those translations should be softened, or every other translation should be updated, but then shouldn't it be 6 kyu? Nasty situation overall :/

But why are JS tests so restrictive? Many other translations don't require any optimizations, and that makes sense for 7kyu.

Are we trying to learn to code or doing a math class?

You can choose literally every other kata to solve, you do not need to solve math kata if you do not like them :)

Haskell translation

Description has also been updated to clarify that indexing is 1-based.

Are we trying to learn to code or doing a math class? why test giant numbers that require optimizaton of code on a 7 kyu?
