Let = {a, b}. For each of the following Grammars. Give one string of size >0 generated by the grammar. Indicate whether the grammar is Regular or not. If yes, prove that the language generated by the grammar is Regular. Hint: a. Generate a string of size >0 b. Check if the grammar verifies the property of Regular Grammars. c. If yes Construct the NFA that recognizes L(G). SaAAaBBaBbBcBd a. stringw= b.Grammar G1 is c. If yes Construct the NFA that recognizes L(G)..
