Write down the instructions for a single-tape Turing machine that interchanges
the two letters x and y that occur somewhere on the input tape and are separated by
blank cells. The initial position of the tape head is at a blank cell somewhere
between the x and y. It is not known whether x is to the left of y or to the right of y.
Design a Turing Machine that takes 2 unary numbers on the tape, where the first number is greater than the second number, and computes and writes a unary number to the tape that is the first number minus the second number.
Design a Turing Machine that accepts strings over the alphabet (a,b) that always ends with 'aaa'.
