Show that the following grammars are ambiguous (find 2 unique parse trees for a single string for each). Then find an equivalent grammar that is not. a. G1a = ({S, a, b}, {a, b}, P, S) where P = {SSS | asa | bSb | asb | bsa | ^ } HINT: What is L(G)? b. G1b= ({S, a, b}, {a, b}, P, S) where P = {S→ asb | aasb | ^ } HINT: What is L(G) ? Introduce a new nonterminal. Show that the following grammars are ambiguous (find 2 unique parse trees for a single string for each). Then find an equivalent grammar that is not. a.
