Question 1

What is the key characteristic of a Deterministic Finite Automaton (DFA)?

Has multiple transitions for each input
Has exactly one transition for each input
Can change states without consuming input

💡 Hint: Recall the distinction between deterministic and non-deterministic.

Question 2

True or False: NFAs can be converted to equivalent DFAs.

True
False

💡 Hint: Consider the implications of the Equivalence Theorem.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design an NFA that recognizes the language of all strings over {0,1} with at least one '01' substring. Convert this NFA to a DFA using the Subset Construction Algorithm and show step-by-step state transitions.

💡 Hint: Outline the NFA first clearly, then define transitions capturing ε-closures.

Challenge 2 Hard

Discuss the implications of using NFAs versus DFAs in a real-world application such as a compiler. Which might be better in which scenarios? Provide examples.

💡 Hint: Consider the different stages of compiler design when making your choice.
