7. 15 Points For a regular expression r, we use L(r) to denote the language it represents. For each of the following regular expressions r, find an NFA that accepts L(r). (b). L((a +b+A) b(a bb)) し(...
THEOREM 3.1 Let r be a regular expression. Then there exists some nondeteministic finite accepter that accepts L (r) Consequently, L () is a regular language. Proof: We begin with automata that accept the languages for the simple regular expressions ø, 2, and a E . These are shown in Figure 3.1(a), (b), and (c), respectively. Assume now that we have automata M (r) and M (r) that accept languages denoted by regular expressions ri and r respectively. We need...
Find an NFA that decides L(aa (ab)). Present a regular expression for the language LR.
Find an NFA that accepts the language L (aa* (ab + b))
Please include all steps. Thanks Find an NFA that decides L(aa(a+b). Present a regular expression for the language LR.
-Find a left-linear grammar for the language L((aaab*ba)*). -Find a regular grammar that generates the language L(aa* (ab + a)*).-Construct an NFA that accepts the language generated by the grammar.S → abS|A,A → baB,B → aA|bb
(a) (5 Points) Construct an equivalent NFA for the language L given by the regular expression ((a Ub) ab)*. Please show the entire construction, step-by-step, to receive full points.
(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...
For each of the following regular expressions, use (11.2.3) to construct an NFA. a. (ab)* b. a*b* c. (a + b)* d. a* + b*
Describe, as precisely as possible, the language generated by each of the following regular expressions. The alphabet is {a, b} (1) (aaa)* b(bb)* (2) abab(ab)* (3) b (e U a) b (4) a(aa) (bb)* UE*baa
Let A={a,b,c}. Describe the language L(r) for each of the following regular expressions: (a) rFab*c; (b)r=(abuc)*; (c) r=abuc*.
