Consider the languages L and L: L = {ww | w ∈ {a,b}∗}, all even-length strings of as and bs whose first and second halves are equal, and its complement L = {w | w ∈ {a,b}∗ ∧ w 6∈ L}, all strings of as and bs that are not in L. One of these languages is a CFL and the other is not. Either show that L or L̅ is context free by giving (design and formalize) either a PDA that recognizes it, or a CFG that generates it. Explain precisely why your PDA or CFG generates exactly L or L̅ .
If a language L ⊆ Σ∗ is recognized by a FA, then there is an NFA M = (K,Σ,δ,s0,F) with |F|= 1 such that L = L(M).
1.a Using a Cross Product method, construct a minimal DFA of w ∑ (a, b) *, where Number of 'a' in a string w mod 2=0 and number of 'b' in a string w mod 2=0 b.Design a minimal Deterministic Finite Automata (DFA) for ∑ = (a, b)
1) Given the alphabet as {0, 1}, write a DFA for the following three regular languages.(Give the complete description of the DFA with transition function as a table and also as a transition graph) (i) L = {w | w is a string of even length} (ii) L = {w | |w| mod 3 = 0} (iii) L = {w | w contains the string 001 as a substring} 2)Describe the extended transition function on a string recursively using transitions one symbol at a time for the three automata of the above problem. (i) A string (of length >=4) that belongs to the language (II) A string (of length >=4) that does not belong to the language
Consider the following languages over the alphabet Σ = {a, b}: 1. L1 = {xwx : x, w ∈ Σ∗}2. L2 = {xwx : x, w ∈ Σ∗, |w| = 1}3. L3 = {xwx : x, w ∈ Σ∗, |x| = 1} For each language, decide whether it is regular or not regular. Prove each of your claims. If you construct a FA or a regular expression, you do not need to prove the correctness of your construction.
Please prove or disprove: If a language L ⊆ Σ∗ is recognized by a FA, then there is an NFA M = (K,Σ,δ,s0,F) with |F|= 1 such that L = L(M).
