We have no experience with Scala, so if someone is willing to help us, that would be helpful.

I've worked with Scala a good amount, so I will get around to submitting a Scala version eventually if nobody else does.

Scala is compatible with Java. The Java version has been implemented, should I just remake this in Scala? Or do you allow for slight logic changes? For example, tail recursion.

@giiita if that is the idiomatic way to implement it in Scala, go for it. If that is "optimization", it will end up on the tuned scoreboard.
