2.5 Give informal descriptions and state diagrams of pushdown automata for the languages in Exercise 2.4. question for 2.4 that you will need for 2.5 2.4 Give context-free grammars that generate the following languages. In all parts, the alphabet Σ is {0,1}. b. {w| w starts and ends with the same symbol}
I'm having a hard time with section 2.5 part B. Despite multiple attempts, I can't seem to get it right. To address part B of 2.5, the question from 2.4 is required.
The issue pertains to pushdown automata, and it would be immensely helpful if you could provide a visual representation illustrating the process you used to arrive at your solution.
I've included my incorrect answer for your reference. Could you assist me in pinpointing why my approach is flawed? My focus is solely on resolving the problem with question 2.5 part B.
