Challenge Problems

Push your limits with challenges.

Question 1

Construct an NFA for the regular expression '(a|b)*c'. Outline the states and transitions.

💡 Hint: Remember to include epsilon transitions where needed.

Question 2

Prove the statement: For every NFA, there exists a corresponding DFA using subset construction.

💡 Hint: Think about maintaining an active set of states through input consumption.
