Is FSM is DFA or NFA ??
If it is DFA,
If we have a word with n bits long, then we require (n+2) states to recoginese that.
Ex: to accept aa over alphabet, we need to 4 states.
So if we have one word of length n, we need (n+2) states DFA.
For other words also we require same number of states, then it would become (n+2) states.
Even after minimising the above DFA, we will have (n+2) states only,
please correct me if iam wrong.
