Question 2. Let Σ= {1}. Design a Turing Machine M that adds a copy of the input string w to the tape resulting in ww. That means starting from the initial configuration qow, the machine terminates at a final state once the tape contains the string ww. For example, assuming that the tape's content is initially 111b (where b indicates the blank is a non-alphabet tape symbol at the end of the string 111, the machine terminates in an accept state with the tape content being 111111b. We say the machine outputs 111111.

Question 2.
Let >= {1}. Design a Turing Machine M that adds a copy of the input string w to the tape resulting
in ww. That means starting from the initial configuration qow, the machine terminates at a final
state once the tape contains the string ww.
For example, assuming that the tape's content is initially 111b (where b indicates the blank is a
non-alphabet tape symbol at the end of the string 111, the machine terminates in an accept state
with the tape content being 111111b. We say the machine outputs 111111.
