Closed until further notice :)

Thanks for helping me figure out what was wrong!

And for which inputs do you get an error? Which errors?

If you mean the if (n==0) then return {0}, yes i tried that

AFAIK you can, as I did it in the past and it seems all fine now: which problem are you getting for it?

Have you checked the other messages from Java users down below?

I do speak Italian :D
E a tal proposito.. mi sfugge qualcosa o davvero non è possibile far copia/incolla su questa piattaforma?
Non credo di resisterci a lungo se è così XD

Got a working solution in Java, running Examples passes without problems but attempting fails without giving a proper reason.
I rebuilt the Junit Test locally and had no problems there.
