This Hard Theory of Computation (Automata) MCQ checks one syllabus fact.
The question is: “What is the function or purpose of Pushdown automaton?”
The accepted answer is A. An automaton that uses a stack to recognize context-free languages.. An automaton that uses a stack to recognize context-free languages is the fact required by What is the function or purpose of Pushdown automaton option A Option B A property of a problem indicating whether an algorithm can be constructed that always provides a correct yes no answer does not match the stem it is a near-miss used to catch incomplete recall of An automaton that uses a stack to recognize context-free languages Option C A finite non-empty set of symbols used to construct strings in a formal language does not match the stem it is a near-miss used to catch incomplete recall of An automaton that uses a stack to recognize context-free languages Remaining alternatives A visual representation showing.
- A. An automaton that uses a stack to recognize context-free languages. ✓
- B. A property of a problem indicating whether an algorithm can be constructed that always provides a correct yes/no answer.
Why not B: “A property of a problem indicating whether an algorithm can be constructed that always provides a correct yes/no answer.” is not correct. The accepted answer is A. An automaton that uses a stack to recognize context-free languages.. An automaton that uses a stack to recognize context-free languages is the fact required by What is the function or purpose of Pushdown automaton option A Option B A property of a p
- C. A finite, non-empty set of symbols used to construct strings in a formal language.
Why not C: “A finite, non-empty set of symbols used to construct strings in a formal language.” is not correct. The accepted answer is A. An automaton that uses a stack to recognize context-free languages.. An automaton that uses a stack to recognize context-free languages is the fact required by What is the function or purpose of Pushdown automaton option A Option B A property of a p
- D. A visual representation showing how an automaton moves between states based on input symbols.
Why not D: “A visual representation showing how an automaton moves between states based on input symbols.” is not correct. The accepted answer is A. An automaton that uses a stack to recognize context-free languages.. An automaton that uses a stack to recognize context-free languages is the fact required by What is the function or purpose of Pushdown automaton option A Option B A property of a p
Correct answer
