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.
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.
