The servers have some problems now, but it could also indicate a not so efficient solution.

I am solving in Haskell, and I encountered a problem: I kept getting the error
Aggregate error, or
gateway timeout.
Is this the server issue, or some other problem, or maybe I just have to submit in another time?

A minor minor correction: proofreading, not provereaadieng. :P

How can we have a chocolate bar with dimensions (1, -1)?
In the description for Haskell it says if there are no chocolates then the function ought to return 0, but my function that does return 0 is not accepted.
Please tell us what results are expected exactly.
