Difficulty: Hard
About this MCQ
This Hard Theory of Computation (Automata) question asks: In computer science, Pumping lemma refers to which of the following? The correct choice is B. A property used to prove that certain languages are not regular by showing they cannot be 'pumped' while remaining in the language.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Theory of Computation (Automata) items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Theory of Computation (Automata) so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Theory of Computation (Automata) item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. The sequence of production rule applications used to generate a string from a grammar's start symbol.
Why not A: “The sequence of production rule applications used to generate a string from a grammar's start symbol.” does not fit this question. The answer is A property used to prove that certain languages are not regular by showing they cannot be 'pumped' while remaining in the language..
- B. A property used to prove that certain languages are not regular by showing they cannot be 'pumped' while remaining in the language. ✓
- C. A finite sequence of symbols drawn from an alphabet.
Why not C: “A finite sequence of symbols drawn from an alphabet.” does not fit this question. The answer is A property used to prove that certain languages are not regular by showing they cannot be 'pumped' while remaining in the language..
- D. A class of formal languages recognized by a linear-bounded automaton, more powerful than context-free languages.
Why not D: “A class of formal languages recognized by a linear-bounded automaton, more powerful than context-free languages.” does not fit this question. The answer is A property used to prove that certain languages are not regular by showing they cannot be 'pumped' while remaining in the language..
