Difficulty: Easy
About this MCQ
This Easy Theory of Computation (Automata) MCQ checks one syllabus fact.
The question is: “Identify the correct definition of String (formal language).”
The accepted answer is C. A finite sequence of symbols drawn from an alphabet.. Identify the correct definition of String formal language is answered by A finite sequence of symbols drawn from an alphabet option C Option A The sequence of production rule applications used to generate a string from a grammar's start symbol does not match the stem it is a near-miss used to catch incomplete recall of A finite sequence of symbols drawn from an alphabet Option B The process of reducing a deterministic finite automaton to the smallest possible number of states while preserving its language does not match the stem it is a near-miss used to catch incomplete recall of A finite sequence of symbols drawn from an alphabet Remaining alternatives A grammar for which some string can be generated.
