Theory of Computation (Automata)
Identify the correct definition of String (formal language).
Difficulty: Easy
About this MCQ
This Easy Theory of Computation (Automata) question asks: Identify the correct definition of String (formal language). The correct choice is C. A finite sequence of symbols drawn from an alphabet.. 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 finite sequence of symbols drawn from an alphabet..
- B. The process of reducing a deterministic finite automaton to the smallest possible number of states while preserving its language.
Why not B: “The process of reducing a deterministic finite automaton to the smallest possible number of states while preserving its language.” does not fit this question. The answer is A finite sequence of symbols drawn from an alphabet..
- C. A finite sequence of symbols drawn from an alphabet. ✓
- D. A grammar for which some string can be generated by more than one distinct derivation tree.
Why not D: “A grammar for which some string can be generated by more than one distinct derivation tree.” does not fit this question. The answer is A finite sequence of symbols drawn from an alphabet..
Correct answer
C. A finite sequence of symbols drawn from an alphabet.
Explanation
A finite sequence of symbols drawn from an alphabet option C is the accepted answer to Identify the correct definition of String formal language Option A The sequence of production rule applications used to generate a string from a grammar's start symbol does not fit this question Option B The process of reducing a deterministic finite automaton to the smallest possible number of states while preserving its language does not fit this question Option D A grammar for which some string can be generated by more than one distinct derivation tree does not fit this question For this Theory of Computation Automata question the accepted answer is A finite sequence.
