27 Find an NFA that accepts the set of binary strings beginning with 010 or ending with 110.

28
28 Comment: For every NFA there is an equivalent NFA that has only one initial state and only one accepting (final) state.

31 Construct a NFA that accepts the language: (a) The set of binary strings that contain at least three occurrences of the substring 010.

32
32 Construct a NFA that accepts the language: (b) The set of binary strings that contain both substrings 010 and 101.
