Question

Hello, I'm having difficulty with this problem and its accompanying with part A. I'm unsure of what to do. Could you provide a visual representation or a diagram to guide me through solving both parts? I don't want words just a drawing of the pushdown automaton

All I require assistance with is question 2.7, particularly a visual representation of the pushdown automaton. Kindly label the components so I can distinguish between part A and part B.

My request is solely for assistance with question 2.7. However, question 2.6 is necessary to answer 2.7. Once again, my focus is solely on question 2.7. Could you please provide a picture for both parts of the pushdown automaton?
