1. (a) Give state diagrams of DFA’s recognizing the following languages. That alphabet is Σ = {a,b} L1 = {w | w any string that does not contain the substring aab} L2 = {w | w ∈ A where A = Σ*− {a, aa, b}} 2. (a) Give state diagrams of DFA’s recognizing the following languages. The alphabet is {0, 1}. L3 = {w | w begins with 0 ends with 1} (b) Write the formal definition of the DFA...

Give state diagrams (pictures) for Turing Machines that decide the following languages over the alphabet {0.1}: 1. {w | w contains an equal number of 0s and 1s} 2. {w | w does not contain twice as many 0s as 1s}.
100% rate Problem 4. (Sipser, 1.7 p.84) Give state diagrams of NFAs with the specified number of states recognizing each of the following languages. In all parts, the alphabet is 10,1) 1. The language 10} with two states 2. The language ww ends with 00) with three states. tates
Problem 2 (20 points). Give context-free grammars that generate the following languages. In all parts, the alphabet Sis {0, 1} 1. {w w contains at least two Os} 2. {ww contains a substring 010) 3. {w w starts and ends with the same symbol} 4. {ww = w that is, w is a palindrome }
1. Give a DFA for each of the following languages defined over the alphabet Σ (0, i): a) (3 points) L={ w | w contains the substring 101 } b) (3 points) L-wl w ends in 001)
Give the regular expressions of the following languages (alphabet is ab): a. {w | w has a length of at least three and its second symbol is a b} b. {w | w begins with an a and ends with a b} c. {w | w contains a single b} d. {w | w contains at least three a's} e. {w | w contains the substring baba} d. {w | w is a string of even length} e. The empty...
1(a)Draw the state diagram for a DFA for accepting the following language over alphabet {0,1}: {w | the length of w is at least 2 and has the same symbol in its 2nd and last positions} (b)Draw the state diagram for an NFA for accepting the following language over alphabet {0,1} (Use as few states as possible): {w | w is of the form 1*(01 ∪ 10*)*} (c)If A is a language with alphabet Σ, the complement of A is...
Unless otherwise noted, the alphabet for all questions below is assumed to be Σ (ab). Also note that all DFA's in your solutions should have one transition for each state in the DFA for each character in the alphabet. 1. (6 marks) This question tests your comfort with "boundary cases" of DFA's. Draw the state diagrams of DFAs recognizing each of the following languages. (a) (2 marks) L = {c) fore the empty string. (b) (2 marks) L (c) (2...
