Difficulty: Hard
About this MCQ
This Hard Theory of Computation (Automata) MCQ checks one syllabus fact.
The question is: “Select the correct name for: an operation on a set of symbols or strings that produces the set of all possible concatenations, including the empty string.”
The accepted answer is A. Kleene star. Select the correct name for an operation on a set of symbols or strings that produces the set of all possible concatenations including the empty string is answered by Kleene star option A Option B DFA-NFA equivalence does not match the stem it is a near-miss used to catch incomplete recall of Kleene star Option C Universal Turing machine does not match the stem it is a near-miss used to catch incomplete recall of Kleene star Remaining alternatives Epsilon transition fall outside the same rule and should be eliminated once Kleene star is identified Theory of Computation Automata questions of this type reward precise definitions rather than approximate associations Theory of Computation Automata recall of this distinction is a regular.
