Question
Let L be the set of exactly those strings over the alphabet {a, b, c, g} whose last symbol is either a or g. Language L is accepted by a (noneterministic) finite automaton M = (Q, E, 5, q, F), where: E = {a, b, c, g}, Q= {q, s}, F= {s} and it is your task to complete the transition function 5 (given below) by filling all the editable empty spaces. q, a, [qs11] q, b, [q14] q, c, [q13] q g, [qs12] q, \lambda, [noneq]

- 2. Let RE be the set of regular expressions over alphabet E = {0, 1}, and for r E RE, let L(r) be the language denoted by r. Consider the claim: VL E P(E*),Vr1, r2 E RE, (|L(r1)| > 1 A L \ L(r2) = L(r1)) = L is regular Either prove this, or find L, rı and r2 that provide a counter-example.arrow_forwardFor a Turing machine M, (M) refers to the binary representation of M. For a Turing machine M, L(M) contains the set of all strings accepted by M. For a Turing machine M and an input x € {0,1}*, Steps(M, x) refers to the number of steps taken by M to execute on x before it halts. Here, one step of execution of M on x = one movement (left or right) of the tape head. For a Turing machine M and an input x = {0,1}*, we define the following: ReachCells(M,x) = {i : M reaches ith tape cell when M is executed on x} Informally, it contains all locations on the tape that are visited when M is ecuted on x. The leftmost location on the tape is the first tape cell, the location next to it is the second tape cell, and so on. A string w₁ is an anagram of w2 if w₁ can be obtained by rearranging the alphabets of w2. Formally, if w₁ is an n length string, wê is called an anagram of w₁ if there exists a permutation à on n elements such that π(w₁) = W2.arrow_forwardprogramm must be solved by python .

- Draw a deterministic finite automaton (DFA) that recognizes the language consisting of strings overthe alphabet {a,b} which contain either exactly two a's (which need not be consecutive) and anynumber of b's, or exactly two b's (which need not be consecutive) and any number of a's (and containsonly such strings.)

- Draw a nondeterministic finite automaton (NFA) that recognizes the language of strings of lowercasealphabetic characters which don't violate the rule "'i' before 'e' except (directly) after 'c'." Thealphabet should be just the letters 'c', 'e', 'i', and 'x', where 'x' will stand for all lowercase letters otherthat 'c', 'e', and 'i.'

For example, it accepts the wordsY(gamma sigh), aa, aaa,aabbbbaacc, but it rejects the words a, baba, cbbba. Write the transition function of the automaton as a table and draw the automaton in the form of a transition diagram. Try to design the simplest possible automaton, i.e., an automaton with the smallest number of states.arrow_forward
