Mostly directed at the OP:
I'm mostly a lurker here but I've learned a lot here. The tone of this
list is mostly "teach a man to fish", not "give a man a fish" (from the
old saying "give a man a fish and you feed him for a day; teach a man to
fish and you feed him for life". To that end, answers tend to point out
and explain how to solve the problem so that the questioner learns. Just
providing the answer does not promote learning. Or to build on the adage
above, giving the solution merely solves today's problem; teaching how
Postfix works solves the future problems as well.
