The purpose of you partner is to give you someone
with whom you can discuss problem details without
it being cheating. I EXPECT EVERYONE TO DO ALL
THE WORK. In other words, do not split the work
between you and your partner.

NOTE:
I encourage you to ask general questions of anyone
in the class. I think the student answering benefits
as much (if not more) as the student asking questions.
Just don't share specific implementation details or
look at each other's solutions.
