Difficulty: Hard
About this MCQ
This Hard Theory of Computation (Automata) MCQ checks one syllabus fact.
The question is: “Which of the following best names the concept in which an automaton that uses a stack to recognize context-free languages?”
The accepted answer is B. Pushdown automaton. Pushdown automaton is the person body or term that satisfies Which of the following best names the concept in which an automaton that uses a stack to recognize context-free languages option B Option A Regular expression does not match the stem it is a near-miss used to catch incomplete recall of Pushdown automaton Option C Finite automaton does not match the stem it is a near-miss used to catch incomplete recall of Pushdown automaton Remaining alternatives Chomsky hierarchy fall outside the same rule and should be eliminated once Pushdown automaton 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.
