Give a DFA/NFA to recognize L = { w | w contains exactly 2 a’s, 3 b’s and no c’s. Σ = {a,b,c} }
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...
Question 1. Let S = {a,b}, and consider the language L = {w E E* : 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”62m : n > 0} = {1, abb, aabbbb, aaabbbbbb, ...} Find production rules for a grammar that generates L.

Design an NFA with at most 5 states for the language (without epsilon transitions) L2= {w ∈ {0, 1}∗ | w contains the substring 0101} Provide the formal 5 tuples(Q,Σ, δ, q0, F) for the NFA Draw/provide a state diagram for your NFA Provide at least three test casesthat prove your NFA accepts/rejects the strings from the language
Construct context-free grammars that generate each of these languages: A. tw E 10, 1 l w contains at least three 1s B. Hw E 10, 1 the length of w is odd and the middle symbol is 0 C. f0, 1 L fx l x xR (x is not a palindrome) m n. F. w E ta, b)* w has twice as many b's as a s G. a b ch 1, J, k20, and 1 or i k
19. Construct minimal NFA that all accepts all strings of {a,b} and L={ambn|m,n>0} Corrected question : 19. Construct minimal FA that all accepts all strings of {a,b} and L={a^mb^n|m,n>0}
