Difficulty: Medium
About this MCQ
This Medium Theory of Computation (Automata) MCQ checks one syllabus fact.
The question is: “A sequence of characters that defines a search pattern, corresponding to regular languages. What is this concept called?”
The accepted answer is D. Regular expression. A sequence of characters that defines a search pattern corresponding to regular languages What is this concept called is answered by Regular expression option D Option A Non-deterministic finite automaton NFA does not match the stem it is a near-miss used to catch incomplete recall of Regular expression Option B Chomsky hierarchy does not match the stem it is a near-miss used to catch incomplete recall of Regular expression Remaining alternatives Finite automaton fall outside the same rule and should be eliminated once Regular expression 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 item in FPSC PPSC NTS and CSS.
- A. Non-deterministic finite automaton (NFA)
Why not A: “Non-deterministic finite automaton (NFA)” is not correct. The accepted answer is D. Regular expression. A sequence of characters that defines a search pattern corresponding to regular languages What is this concept called is answered by Regular expression option D Option A Non-determ
- B. Chomsky hierarchy
Why not B: “Chomsky hierarchy” is not correct. The accepted answer is D. Regular expression. A sequence of characters that defines a search pattern corresponding to regular languages What is this concept called is answered by Regular expression option D Option A Non-determ
- C. Finite automaton
Why not C: “Finite automaton” is not correct. The accepted answer is D. Regular expression. A sequence of characters that defines a search pattern corresponding to regular languages What is this concept called is answered by Regular expression option D Option A Non-determ
- D. Regular expression ✓
