I saw you made a postfix expression tree and stack for a user the other day. I was wondering if I could also buy that code or similar code. I know it is a very easy project and shouldn't take more than a couple hours to complete. I would love to have it in 12 hours or less. I will pay more to have it a higher priority, and I will, of course, credit you for writing the code. I would just like to see and use that implementation with some of the kids I tutor and I am overloaded with work.
