Consider again the finite-state automaton of exercise 3.
a. To what state does the automaton go when the symbols of the following strings are input to it in sequence, starting from the initial state?
(i) bb (ii) aabbbaba (iii) babbbbbabaa (iv) bbaaaabaa
b. Which of the strings in part (a) send the automaton to an accepting state?
c. What is the language accepted by the automaton?
d. Find a regular expression that defines the language.
The state for which given finite-state automaton, goes for each sequence of inputs.
The automaton is as follows.
The automaton given has only two inputs and the set of states includes four states . From these states, is the accepting state.
Four sequences of inputs have been given as follows.
The automaton that we are discussing here is in the initial state . For the both inputs , responses and for , the automaton goes to and for , the state changes to
The sequences of strings that bring the automaton to an accepting state.
The accepted language of the automaton.
The regular expression that represents the language accepted by this automaton.
