Trees generally have a trunk; branches off that trunk, and leaves or
nodes along those branches that may turn into other branches.  Let's say
a tree exists it could have several main branches which could be further
described by which direction they emanate from the trunk.  So you have a
north main branch pointing north, with a second north branch that also
connects to the trunk directly, you have a secondary north branch.
After that, number the nodes going down each of those branches and then
put descriptive text as to what's at that location.  Without a whole lot
of main branches compass directions may not be needed and each main
branch could be described in terms of information it is to hold.  There
might be a columns branch; a rows branch, and a diagonals branch in this
particular case.  So, trunk; mnb1 main north branch 1 might be useful
with mnb1l2 pointing at main north branch left node 2 could be a way to
document this for yourself and keep it straight in your head.  Hth.

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.
