1. Consider the NFA defined by the state diagram below. Follow the algorithm seen in
class and in our textbook to construct an equivalent DFA. Please only include the
states reachable (in one or more transitions) from the start state. (Your solution can
be either the table or the state diagram, or both if you wish.)

(ii) Derive the canonical POS (product of maxterms) for F.
(iii) Draw the truth table, clearly marking which rows are minterms of F and
which rows correspond to maxterms of F.

function of n and briefly justify it.
