1.A: Let Sigma be {a,b}. Draw a DFA that will accept the set of all strings x in which the last letter of x occurs exactly twice in a row. That is, this DFA should accept bbabbbaa (because there are two a's at the end), and aaabb (two b's), but should not accept aaa (3 a's in a row, and 3 is not exactly 2), nor single letter words such as 'b', nor baba, etc.
Automata, Languages & Computation 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: We were unable to transcribe this imageWe were unable to transcribe this imageb b b 1,1 2,3 3,2 a a b b b 1,1 2,3 3,2 a 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.
Give a DFA over {a,b} that accepts all strings containing a total of exactly 4 'a's (and any number of 'b's). For each state in your automaton, give a brief description of the strings associated with that state.
1. Construct a DFSM to accept the language: L = {w € {a,b}*: w contains at least 3 a's and no more than 3 b's} 2. Let acgt} and let L be the language of strings consisting of repeated copies of the pairs at, ta, cg, gc. Construct both a DFSM to accept the language and a regular expression that represents the language 3. Let a,b. For a string w E ', let W denote the string w with the...
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.
Give a DFA which will accept all strings of length 3n; n =0, 1. 2. ,,, over ∑ = {a.b}*
Construct the state digraph (including accept states) of a Moore machine that accepts all strings that start with b and end with baa. The input alphabet is A = {a, b].
