Unformatted text preview: (d) to obtain the initial state of add a new state and add-transitions too all states which were ﬁnal states in . The newly added state is the initial state of . (e) there is only one ﬁnal state, namely the state which was initial state in Why this works: A word is accepted in if there is a path from the initial state to the ﬁnal state. But given the con-struction this means that in there is a path from the initial state to one of the ﬁnal states. Therefore if if . The above argument works the other way around, therefore implies .
