Our goal is to construct a deterministic one-tape Turing machine that accepts strings overΣ = {a, b} which are palindromes. A palindrome is a string which is the same when read forwards andbackwards, for example abbabba. The Turing machine should operate in the following way:1. Remember the first character of the input in the state control, and erase this character (replace it witha blank).2. Move the head to the last (right-most) character of the input.3. Verify that this character is the same character as the one stored in the state control. If it is, deletethis character. If it is a different character, immediately halt and reject.4. Move the head to the left-most character of the input.5. If there are any characters left on the input, repeat from step 1.6. If in step 1 or 3 the tape is empty (i.e. all characters of the input have been erased), halt and accept. Question 2.

Question

Our goal is to construct a deterministic one-tape Turing machine that accepts strings over
Σ = {a, b} which are palindromes. A palindrome is a string which is the same when read forwards and
backwards, for example abbabba. The Turing machine should operate in the following way:
1. Remember the first character of the input in the state control, and erase this character (replace it with
a blank).
2. Move the head to the last (right-most) character of the input.
3. Verify that this character is the same character as the one stored in the state control. If it is, delete
this character. If it is a different character, immediately halt and reject.
4. Move the head to the left-most character of the input.
5. If there are any characters left on the input, repeat from step 1.
6. If in step 1 or 3 the tape is empty (i.e. all characters of the input have been erased), halt and accept.
