Construct an NFA for the regular expression (a|b)*c and illustrate the transitions.
💡 Hint: Start with separate branches for 'a' and 'b', then connect them to the state for 'c'.
Prove using Arden's Lemma that the regular expression ab* can yield an equivalent NFA.
💡 Hint: Remember to include the transition for the first 'a' leading to further cycles.
