I need help with the following code. I have the correct production rules but can't figure out how to correctly determine the next generation if the current generation isn't: A, B, +, or -. If the current generation is A my code will correctly display the next generation as: +B-A-B+. However, if I start of with +B-A-B+ as the current generation, the next generation is only computed as: +. I understand I need to implement a for loop for the getProd() method but I can't seem to figure this out and I have been going crazy because I can't figure it out.
