Given: Language L2 = {w ϵ {a,b}* | w contains substring aab} Construct the DFA representing the given language L2. Assume the layout of the DFA is as follows: ->A->B->C->D*. That is, the number of states are four (4) and A is the starting state and D is the accepting state. How many self-loop edge/s in the constructed DFA representing the given language L2?
2. A lexical analyzer uses the following patterns to recognize three tokens T₁, T₂, and T, over the alphabet {a,b,c} which are: T₁: a?(bic)*a T₁: b?(alc)*b T: c?(bla)*c Note that 'x?' means 0 or 1 occurrence of the symbol x. Note also that the analyzer outputs the token that matches the longest possible prefix. If the string bbaacabc is processes by the analyzer, which one of the following is the sequence of tokens it outputs?. Explain your argument. Τ.Τ.Τ., (B) TT. (C) T,T, (D)T,T, (E)T,T
3. Given the set of codewords K = {ryx, rxry, ryyr, yyrr, xIryy, IryYr, YYYYT, Yxyxyy}. Determine whether or not the code is uniquely decipherable. If a code is not uniquely decipherable, construct an ambiguous sequence.
Given: Language L3 = {w ϵ {a,b}* | w starts in ab and ends in bb} Construct the DFA representing the given language L3. Assume the layout of the DFA is as follows: ->A->B->C->D->E*. That is, the number of states are five (5) and A is the starting state and E is the accepting state. How many self-loop edge/s in the constructed DFA representing the given language L3?

5. Let A = {(G, a) | G is a CFG, a is a terminal symbol, and L(G) na' # Ø.} Show that A is decidable.
QUESTION 4 L2 = {p"@g": i20}, E= {p, q}. For example, if i= 2, so the string will be pppppp@qqqg. i) Draw the state diagrams for the TM L2. ii) Give the formal definition of the TM for L2. 2
A uwuified sentence is sentence that has been transformed using a made-up Internet language in which some of the letters in the words are replaced by something else. The exact scheme is described below: Any uppercase/lowercase R or L is replaced by w/w, respectively. • If we encounter an o/o in a word, check if the previous letter (if it exists) is an M/m or N/n. If the previous letter is one of these, insert the lowercase letter y in between them, regardless of the capitalization of the other letters. • All other characters are left unchanged. Some examples: Professor will be converted to Pwofessow (There are two r's that are replaced by w's. Since the two o's aren't proceeded by an M/n or N/n, no y will be inserted.) LLunoacyo will be converted to wwunyoacyo (The two L's will be replaced with two ws according to the first rule. Then the first o will have a y inserted in front of it between then and the o according to the second rule. The last o won't have a y inserted in between…

Which of the following definitions is/are syntactically correct: (i) filter(p, [h|t]) -> case p(h) of true -> [h\filter(p, t)] false -> filter(p, t) end filter(p, []) -> [] (ii) filter(P, []) -> []; filter(P, [H|T]) -> case P(H) of true -> [H[filter(P, T)]; false -> filter(P, T) end. (ii) filter(P, [H|T]) -> case P(H) of true -> [H|filter(P, T)]; false -> filter(P, T) end; filter(P, []) -> 1. O (1) only O (i) only (iii) only O (i) and (i) O None of the above.
13. Draw a deterministic FSM that recognizes strings of 1’s and 0’s specified by each of thefollowing criteria. Each FSM should reject any characters that are not 0 or 1. *(a) The stringof three characters, 101. (b) All strings of arbitrary length that end in 101. For example, theFSM should accept 1101 but reject 1011. (c) All strings of arbitrary length that begin with 101.For example, the FSM should accept 1010 but reject 0101.
