Consider the language L below. (a) Is L a regular language? – Yes, or No. (b) If L is a regular language, design the DFA (using a State Table) to accept the language L, with the minimum number of states. Assume , (c) Suppose the input is “101100”. Is this input string in the language L?
Given language,
a)
Yes, the given language is regular language.
b)
c)
The given string is "101100" is not in the language.
q1 --1--> q2 --0--> q3 --1--> q2 --1--> q3 --0--> q2 --0--> q3 which is not final state.

Question 1: Design a DFA with at most 5 states for the language L1 = {w ∈ {0, 1}∗ | w contains at most one 1 and |w| is odd}. Provide a state diagram for your DFA. Approaching the Solution --since we haven’t really practiced this type of assignment (i.e. had to define our machine based on only having the language given; not the formal 5 tuples), I am providing the steps for how to work through this; you are...
. Let Σ = { a, b } , and consider the language L = { w ∈ Σ ∗ : w contains at least one b and an even number of a’s } . Draw a graph representing a DFA (not NFA) that accepts this language.
Show that the language L defined below is regular: L={w/ w has an even number of O's and 1 is the last symbol)
Let Σ = { a, b } , and consider the language L = { a n : n is even } ∪ { b n : n is odd } . Draw a graph representing a DFA (not NFA) that accepts this language.
Question 1. Let Σ = {a, b}, and consider the language L = {w ∈ Σ ∗ : w contains at least one b and an even number of a’s}. Draw a graph representing a DFA (not NFA) that accepts this language.
Question 1. Let Σ = {a, b}, and consider the language L = {w ∈ Σ ∗ : w contains at least one b and an even number of a’s}. Draw a graph representing a DFA (not NFA) that accepts this language. Question 2. Let L be the language given below. L = {a n b 2n : n ≥ 0} = {λ, abb, aabbbb, aaabbbbbb, . . .} Find production rules for a grammar that generates L.
Question 5. Let Σ = {a, b}, and consider the language L = {a^n : n is even} ∪ {b^n : n is odd}. Draw a graph representing a DFA (not NFA) that accepts this language.
Question 1: Every language is regular T/F Question 2: There exists a DFA that has only one final state T/F Question 3: Let M be a DFA, and define flip(M) as the DFA which is identical to M except you flip that final state. Then for every M, the language L(M)^c (complement) = L( flip (M)). T/F Question 4: Let G be a right linear grammar, and reverse(G)=reverse of G, i.e. if G has a rule A -> w B...
John Doe claims that the language L, of all strings over the alphabet Σ = { a, b } that contain an even number of occurrences of the letter ‘a’, is not a regular language. He offers the following “pumping lemma proof”. Explain what is wrong with the “proof” given below. “Pumping Lemma Proof” We assume that L is regular. Then, according to the pumping lemma, every long string in L (of length m or more) must be “pumpable”. We...
Question 5. Let Σ = {a, b}, and consider the language L = {a n : n is even} ∪ {b n : n is odd}. Draw a graph representing a DFA (not NFA) that accepts this language. Question 6. Give a brief description of the language generated by the following production rules. S → abc S → aXbc Xb → bX Xc → Ybcc bY → Yb aY → aa aY → aaX
