The program prompts the user to input Turing machine instructions. The code for an arbitrary Turing machine is a set of quadruples. The user inputs each entry for each quadruple when prompted. It is recommended that the user prepare the Turing code before interacting with the program (unless the user is comfortable programming Turing machines on the fly).
Run the program from the command line and test out your Turing code on arbitrary pairs of natural numbers.
