is there a reason to not leaving a space? like why cramp them together instead of

return position + roll /* 2

Nice, but parenthesses are unneccesary here :>

I dont think it should be there.

Why the semicolon? It does absolutely nothing here

it means you printed too much information to the console log.

what's wrong? Simple tests and random tests have passed.

STDERR:
Max Buffer reached: Too much information has been written to stdout.
SIGKILL
Process exited prematurely with a SIGKILL signal.

nope, but you're heading in the right direction (even if still far from the goal). Basic geometry knowledge still apply, to solve this type of things.
