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...
Let R = (0*0 ∪ 11)*∪(10). Use the construction from the lecture (given any regular expression, we can construct an NFA that recognizes the described language) to construct an NFA N such that L(N) = L(R). Apply the construction literally (do not optimize the resulting NFA–keep all those ε arrows in the NFA). Only the final NFA is required, but you can get more partial credit if you show intermediate steps
(g) If there is an NFA with s states which accepts a language L, then we can construct a DFA which accepts the same language and has: (circle the smallest correct answer a) s states b) 2s states d) 2 states (h) If there is a DFA which accepts a language A with s states and another whiclh accepts language B with t states, then we can construct a DFA which accepts An B which has (circle the smallest correct...

UueSLIORS! 1. Find the error in logic in the following statement: We know that a b' is a context-free, not regular language. The class of context-free languages are not closed under complement, so its complement is not context free. But we know that its complement is context-free. 2. We have proved that the regular languages are closed under string reversal. Prove here that the context-free languages are closed under string reversal. 3. Part 1: Find an NFA with 3 states...
Finite state machines & Regular Expressions Please select the best option 1. For the following questions Let r, s, t be regular expressions for the same alphabet "á" (left column). Get the property on the right side that produces equality for each regular expression. 2. From the diagram of the solution M = (Σ, Q, s,, F) is respectively: e would be NONE. 3. The following graph corresponds to a diagram of: A. Transition machine and states b. Transition...
Part B - Automata Construction Draw a DFA which accepts the following language over the alphabet of {0,1}: the set of all strings such that the number of 0s is divisible by 2 and the number of 1s is divisible by 5. Your DFA must handle all intput strings in {0,1}*. Here is a methodical way to do this: Figure out all the final states and label each with the shortest string it accepts, work backwards from these states to...
