2.D, B, C, E, A✓ Correct
3.C, E, B, A, D
4.A, D, C, B, E
Solution
The correct answer is D, B, C, E, A
Key Points
To arrange the steps of constructing a finite automaton in the correct order, let's understand the logical sequence:
Problem Statement (D)
The first step is to clearly define the problem that needs to be solved. This involves understanding the requirements and constraints.
Regular Expression (B)
Once the problem is defined, the next step is to represent it using a regular expression, which provides a concise way to describe the language of the problem.
NFA - ϵ (C)
After defining the regular expression, it is converted into a Non-deterministic Finite Automaton with epsilon transitions (NFA-ϵ), which is easier to construct from a regular expression.
DFA (E)
The NFA-ϵ is then converted into a Deterministic Finite Automaton (DFA), which is easier to work with in terms of state transitions.
Minimum State DFA (A)
Finally, the DFA is minimized to produce a Minimum State DFA, which has the least number of states required to recognize the same language.
