Prove that the following languages are not regular. You may use the pumping lemma and the closure of the class of regular languages under union, intersection, and complement. a. {0"1"0"| m, n 2 0} b. (0"1"| m ‡ n) c. (w| w € {0,1)* is not a palindrome) d. (wtw| w,t € (0,1)*)

Each of the following languages is the complement of a simpler language. In each part, construct a DFA for the simpler language, then use it to give the state diagram of a DFA for the language given. In all parts, Σ = {a, b}.{w| w does not contain the substring ab} {w| w does not contain the substring baba} {w| w contains neither the substrings ab nor ba} {w| w is any string not in a∗ ∪ b∗ } ( ∪ is the union )

THEORY OF AUTOMATA ASSIGNMENT # 1 1. Write regular expressions and draw NFA for the following languages over the alphabet Σ = {a, b}: a. All strings that do not end with aa. b. All strings that contain an even number of b’s c. All strings that contain atleast two a’s or exactly two b’s d. All strings that ends with double letters (aa or bb) e. All strings that does not ends with double letter.(can end with ab or ba)

Consider the following class definitions in a hypothetical Object Oriented language that supports inheritance and uses dynamic binding. The language should not be assumed to be either Java or C++, though the syntax is similar. Class P { void f(int i) { print(i); } } Class Q subclass of P { void f(int i) { print(2*i); } } Now consider the following program fragment: P x = new Q(); Q y = new Q(); P z = new Q(); x.f(1); ((P)y).f(1); z.f(1); Here ((P)y) denotes a typecast of y to P. The output produced by executing the above program fragment will be (A) 1 2 1 (B) 2 1 1 (C) 2 1 2 (D) 2 2 2
