Construct the DFA that defines the complement of a*b*
* is ^n
Construct the DFA for (aaa)*. The alphabet is just {a} and then Construct the DFA for (aa)*. The alphabet is just {a}. construct the union DFA. Use the partition algorithm. Then construct the intersection DFA.
Three. Show a DFA over the alphabet {a, b} for the following language via complement construction (as in Exercise l.5.d): {w belongs to Sigma* | w is not in a*b*}.
a. Draw the transition diagram for the DFA
b. Construct a regular expression for the language of the DFA
by computing all the R_ij^(k) regular expressions.
Consider the following DFA: 1 A В C B A C В
For Σ = {a, b}, construct a DFA that accept the sets consisting of all strings with at least one b and exactly two a's. Note: provide input to thoroughly test the DFA.
For ∑ = {a, b}, construct a dfa that accepts the set consisting of all strings with exactly one a
1) Assume ∑ = {a, b}, construct a DFA to recognize: {w | number of a's in w ≥ 2 and number of b's in w ≤ 1}. (seven states) 2) Assume ∑ = {a, b}, construct a DFA to recognize: {w || w | ≥ 2, second to the last symbol of w is b}. (four states) 3) Write a regular expression for: All bit strings that contain at least three 1's.
For ∑ = {a, b}, construct a dfa that accepts the set consisting of all strings with at least one b and exactly two a’s

Question: For = {a,b} construct
the DFA that accepts the language consisting of all strings over
the with no more than
one a.
The DFA constructed should be in a form similar to the below but
obviously built using the above language:

Construct an DFA automaton that recognizes the following language of strings over the alphabet {a,b}: the set of all strings over alphabet {a,b} that contain aa, but do not contain aba.
