4. Let G be the context-free grammar given by the rules

4. Let G be the context-free grammar given by the rules SA0BSSAAA1BBB0 (a) Use the technique of the proof of Theorem 2.20 to construct a pushdown automaton M equivalent to G. You only need to show the state diagram of M. (b) Is L(G) regular? Prove your answer. (Don't confuse regular with context-free here.)
