Question

Examples of what works:

01101101101101

1011101010

1010

0101

Answer 1

Check if this is working..

Below half part of the above figure can be obtained by changing 1 to 0 and 0 to 1. It is like horizontal symmetry present in the states.

thanks, @ankitgupta.1729

The whole DFA is based on this input set {000,111,0101,1010,11011,00100,...}, I was trying to build using minimum number(less than the required number actually) of states which lead to few mistakes.

Mistakes are part of life :P

Like me and you, everyone do mistakes. No one is perfect.

Answer 2

I think is the answer
