Create two basic racket programs implementing turing machine

Write a Turing Machine program to be fed to the [login to view URL] which implements unary subtraction as follows:  the symbols valid for this machines are (), 1, 0,   the input is of the form 0(1s  1s)  the machine subtracts the second series of 1s from the first  the output is of the form 0(1s0s  0s), where the list of 1s is the reminder of the subtraction, the 0s are the elements delted respectively int he first and in the second input.
