1)Construct an NFA M over the alphabet {a, b} such that the language accepted by M consists of strings in which the second to last symbol is b. Make sure M exhibits the two features that a DFA cannot exhibit. Show the transition diagram of your NFA

2)Show a successful execution sequence for the input string ababb. You can show your result by writing an alternating sequence of states and input symbols so that it represents a sequence of transitions of M.

3)Show three unsuccessful executions of M on the input bbababa.
