Let L={w: w is any string in {0, 1} that does NOT contain the substring 01} a) Write the grammar for L (3) b) Construct the machine M for L using the 'complement' closure property by constructing the DFA for L={w: w is any string in {0, 1} that contains the substring 01) and then taking the complement of this machine. (all detailed steps to be shown including conversion of regular expression to NFA, NFA to DFA, and the complement step). (5) c) Trace the string 1001 through the DFA M constructed in step (b). (2)
