(b) Suppose that you were asked to design a
Turing machine that, when started scan-
ning a square on a completely blank tape,
writes the string ababbaab on the tape
and halts scanning the leftmost symbol of
this string. What is the minimal number
of states required in order to accomplish
this?
The state transition diagram for a Turing machine that performs unary increment is shown below.

Show how this Turing machine will process the input "1111111". You are required to show the configuration of the Turing machine at the
beginning of the execution and after each execution step until the Turing machine halts.
