Define nor operation for the language as follows. nor(L1, L2) = {w : w E L1 or w E L2} Show that the family of regular languages is closed under the nor operation. Define nor operation for the language as follows. nor(L1, L2) = {w : w E L1 or w E L2} Show that the family of regular languages is closed under the nor operation.
-. If L and L2 are regular languages, show the the language BothOr Neither is also regular. Both Or Neither is the language that contains strings that are in both L1 and L, or in neither L or L2.
Suppose L1, L2, and L3 are languages and T1, T2, and T3 are Turing machines such that L(T1) = L1, L(T2) = L2, L(T3) = L3, knowing that T3 is recursive (always halts, either halts and accepts or halts and rejects) and both T1 and T2 are recursive enumerable so they may get stuck in an infinite loop for words they don't accept.. For each of the following languages, describe the Turing machine that would accept it, and state whether...
The languages L1 = {anbm | m = n or m = 2n } and L2 = {a n b m | n <= m <= 2n } are context free. a. Choose one of the languages and write a CFG for it. b. Write the PDA that comes from your grammar (part a). Show the first 4 moves it would make on some string in your language (of length at least 4). Be sure to show state, input, and...
2. If L1 and L2 are regular languages, which of the following are regular languages? Provide justification for your answers. a. L1 U L2 b. L1L2 c. L1 n L2
Automata, Languages and Computation Using the languages L1 = { (10)* 1(1+0) + (10)*} and L2 = { a(a*) }, construct an ei NFA that accepts the concatenation of the languages L1L2. Using the languages L1 = { (10)* 1(1+0) + (10)*} and L2 = { a(a*) }, construct an ei NFA that accepts the concatenation of the languages L1L2.
For each of the following statements, where L1, L2, and L are languages over some alphabet Σ, state whether it is true or false. Prove your answer. • ∀L,(∅ or L+) = L∗ • ∀L1,L2,(L1 or L2)∗ = (L2 or L1)∗
