Question
Can you please help me with this question because i am struggling on how to do this problem. I only need help with question 2.10 and only 2.10 but you need question 2.9 to answer the question for 2.10.
Again I only need help with question 2.10 and can you show something visual to see the answer for the pushdown automaton and can you show the answer step by step so I can follow along.
