Question
Show that the following is regular. Please Construct a DFA to accept the following.
Expert Solution
Step 1
Construct DFA for the language
L = {aa: {a, b}* } is regular
DFA is a collection od 5-tuples and is as follows
DFA = (Q, , , q0, F)
where,
Q: finite set called state
: finite set call alphabets
: Q x -> is a transition function
q0 Q is a start or the initial state
F: final state
DFA = ( {q0, q1, q2, q3}, {a, b}, q0, , q2}
the language will be L = {aa, aba, aaa, abaaba, aaba,.....}
