Construct DFA's Ai, A2, Ag,A, such that L(Ai)-Li, for i {1, 2, 3, 4), where the Li's are as below. Specify each DFA formally, as A - (Q, F) and define all the components Qi, , formally, using the notation in the textbook. (a) Li-X'(ababy : x, *), where 3(a,b) (c) L4 is the set of strings over (a, b that either begin or end (or both) with ab. (d) Ls is the set of strings over {a, b* that contain an odd number of a's and end in at least two b's
