Question 1
What is the purpose of converting NFAs and DFAs into regular expressions?
- To reduce the number of states.
- To provide a more compact representation of patterns.
- To eliminate unnecessary transitions.
💡 Hint: Think about ease of use and representation.
Question 2
True or False: Arden's Lemma helps to create regular expressions from paths in finite automata.

Question 1
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.
Question 2
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.
