Write a program for our CPU to subtract two integers. Assume the following data memory contents:

M[0] = -1

M[1] = M

M[3] = Difference M-N

M is the minuend, and N is the subtrahend ( in other words, we want to compute M-N). The difference should end up in M[3]. You can only use the 9 instructions in our CPU, 9 instructions set file is attached . Do not make up your own instructions.
