What is the output of following program: public class test { public static void main(string[] args) { a a = new a(); a. methodb(); } } class a { public a() { system. out. println("a's constructor is executed"); } public void methoda() { system. out. println("methoda is executed"); } public void methodab() { system. out. println("a's methodab is executed"); } } class b extends a { private int num = 0; public b() { super(); system. out. println("b's constructor is executed"); } public b (int n) { num = n; system. out. println("b's constructor is executed"); } public void methodb() { system. out. println("num is " + num); system. out. println("methodb is executed"); } public void methodab() { system. out. println("b's methodab is executed"); } }

Show that there is a language a ⚆ {0, 1} â— with the following properties: 1. for all x â a, |x| ≤ 5. 2. no dfa with fewer than 9 states recognizes a. hint: you don’t have to define a explicitly; just show that it has to exist. count the number of languages satisfying (1) and the number of dfas satisfying (2), and argue that there aren’t enough dfas to recognize all those languages. to count the number of languages satisfying (1), think about writing down all the strings of length at most 5, and then to define such a language, you have to make a binary decision for each string about whether to include it in the language or not. how many ways are there to make these choices? to count the number of dfas satisfying (2), consider that a dfa behaves identically even if you rename all the states, so you can assume without loss of generality that any dfa with k states has the state set {q1, q2, . . , qk}. now think about how to count how many ways there are to choose the other four parts of the dfa.

Technician a says that if a valve is open when a piston rises to the very top of a cylinder, the piston may actually strike the valve head and cause serious engine damage. technician b says if the camshaft is located in the engine block, then the engine is called an overhead valve engine, ohv engine, or an in-block camshaft. who is right? a. b only b. both a and b c. a only d. neither a nor b
