7. Consider the DFA M3 defined by ({91,92,93,94}, {0,1}, 8, 91, 92}), where 8 is defined by the following table: 0 1 91 94 93 92 92 92 93 92 93 94 94 92 a. Draw the state diagram for this DFA. b. List all strings of length 3 accepted by this DFA. c. This DFA accepts exactly the set of strings in one of the languages given in problem 4 above. Which language? (Justify your answer with clear reasoning - you don't need a formal proof here, just a good argument.)
