About this MCQ
This Medium Theory of Computation (Automata) MCQ checks one syllabus fact.
The question is: “Choose the correct description of Regular expression.”
The accepted answer is C. A sequence of characters that defines a search pattern, corresponding to regular languages.. Choose the correct description of Regular expression is answered by A sequence of characters that defines a search pattern corresponding to regular languages option C Option A A finite automaton that may have multiple possible transitions for a given state and input symbol does not match the stem it is a near-miss used to catch incomplete recall of A sequence of characters that defines a search pattern corresponding to regular languages Option B A language that can be expressed using a regular expression or recognized by a finite automaton does not match the stem it is a near-miss used to catch incomplete recall of A sequence of characters that defines a search pattern corresponding to regular languages Remaining alternatives An.
- A. A finite automaton that may have multiple possible transitions for a given state and input symbol.
Why not A: “A finite automaton that may have multiple possible transitions for a given state and input symbol.” is not correct. The accepted answer is C. A sequence of characters that defines a search pattern, corresponding to regular languages.. Choose the correct description of Regular expression is answered by A sequence of characters that defines a search pattern corresponding to regular languages option C Option A A fi
- B. A language that can be expressed using a regular expression or recognized by a finite automaton.
Why not B: “A language that can be expressed using a regular expression or recognized by a finite automaton.” is not correct. The accepted answer is C. A sequence of characters that defines a search pattern, corresponding to regular languages.. Choose the correct description of Regular expression is answered by A sequence of characters that defines a search pattern corresponding to regular languages option C Option A A fi
- C. A sequence of characters that defines a search pattern, corresponding to regular languages. ✓
- D. An abstract machine with a finite number of states used to recognize patterns in input strings.
Why not D: “An abstract machine with a finite number of states used to recognize patterns in input strings.” is not correct. The accepted answer is C. A sequence of characters that defines a search pattern, corresponding to regular languages..
