Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a DFA with specific transitions and accept states, apply the State Elimination Method to derive its regex.

💡 Hint: Carefully visualize the state transitions during elimination.

Challenge 2 Hard

Using Arden's Lemma, write equations for a DFA, and derive the overall regex for paths leading to the accepting states.

💡 Hint: Keep track of changes in paths as you solve step-by-step.
