QUESTION 1 Let M = {S, I, qo, fs, F) be the DFA such that S={90, 91, 92, 93}, I={a,b}, F={41}, qo=initial state and fs is given by: fs (qo, a) = 41, fs (qo, b) = 42 fs (q, a) = 93, fs (q, b) = 42 fs (q2, a) = 91, fs (q2, b) = 42 fs (q3, a) = 43, fs (q3, b) = 22 i. Construct a state transition diagram of the DFA given the state transition function, fs. ii. DFA can be applied for verification of email password. Justify why DFA is suitable for verification
