Turing Machine for complement of a string in Theory Of Automata

Turing Machine for the complement of a string

Turing Machine in the machine that can convert every 1 to 0 and every 0 to 1.

1. First of all, start the machine.

If there is any 0 on input tape than machine read 0 and write 1.

If there is any 1 on input tape than machine read 1 and write 0.

2. On state 2, there is a loop of;

If there is any 0 on input tape, then machine read 0 and write 1.

If there is any 1 on input tape than machine read 1 and write 0.

3. On state 2, there is a transition of the delta because in the rightmost, always input tape has a delta or can have some other variable instead of the delta.

Accept is the final state where machine halts by successfully accepting the string.

Example of Turing Machine for the complement of a string

Suppose the string is 0101101.

Question: How a Turing machine can convert this into its complement?

The path will be looks like;

Path: Start  2 > 2 > 2 > 2 > 2 > 2 > 2 > accept

After the complement, the string will be looks like;

1010010
