Come now! Are you asking us to do your homework for you, or is it part of
the project to go out into the net and find a wheel, so you don't have
to re-invent it? If the latter, contact me by e-mail.

Plagarism is copying from a single source, research is copying from
multiple sources...

I hope not, because in that case Mr Wogan is going to fail. You don't
need a binary-tree package to solve that problem, or anything remotely
as elaborate. You can do the transformation in one pass with a simple
operator-precedence parser. Recurse when you hit a left parenthesis.

Did you think I felt like telling him that? He has not, by the way,
replied, either to me or to the net. :-)
