Load the following program into the PDP8 and run it. The program starts at address 0200, and expects the switch register to contain some number N at the time when execution begins. The program computes some number, depending on the value of N, and puts the computed number into the accumulator before halting.

Your assignment is (1) to figure out what this program does, and (2) to comment the code as fully as you can. I recommend that you run the program a few times with a variety of (small) values of N. You should start to recognize a pattern. In class on Monday, we will look more closely at this program, and I'll ask you to shorten it and improve your commenting.
