I agree with this. If this hadn't been ranked at 7 kyu, I would have spent a long time working out how to optimally break chocolate in as few "operations" as possible. Clearly that turned out not to be necessary, but I shouldn't have to guess that based on the rating.

Sure, and sure, but it does fail.

It would be very helpful if the "Cheating" tests told me how I was cheating. I keep failing the second one but have no idea why since they aren't in the visible test code. (It does say "should use first argument", but I'm using all the arguments, so I must be misunderstanding the test.)
