RE: trees?

I think that you should sit down with either her or someone  else who fully 
understands the concept, and concentrate on
understanding how trees work, rather than being hung up on the representation.

I'll volunteer to offer some info over skype or phone, and there should be some 
good websites on this, but concepts like this need
to be explained in person/voice, not just by reading about them, although you 
can get a lot that way too.

Take care,
Sina

Subject: trees?

Hi all,
We are doing trees in an algorithms class I am taking. The assignment coming up 
is the "n queens" problem, where you have an n by n
board and must place n queens on the board such that no two queens share the 
same row, column, or diagonal line. To "help" explain
this, the professor is using a tree on the board. I am completely confused! She 
says I do not need to think of it in terms of trees,
yet the only way she explains it is in tree terms, so I am not sure what she is 
talking about. Of course I know about trees, but
when she tries to explain how the code we are looking at relates to the tree in 
terms of what the code is supposed to do, I haven't
a clue as to what she is trying to say. Does anyone have any thoughts on how to 
represent trees, whether in braille or speech, or a
good notation/substitute for a tree? TIA.
