Question

I'm facing significant difficulties with section 2.5, specifically with part B. Despite numerous attempts, I've been unsuccessful in locating the correct solution. In order to address part B of section 2.5, I require the information provided in section 2.4.

The issue revolves around pushdown automata, and having a visual representation demonstrating the steps taken to solve it would be immensely beneficial.

I've attached my incorrect response for your evaluation. Could you assist me in identifying the flaws in my approach? I'm particularly interested in rectifying the problem with question 2.5 part B.

The response provided in the image is inaccurate. It states, "Incorrect. The string 0 is an example."
