Determine the output of the following machine-language program by running it in Pep/8. The left column in each part is the memory address of the first byte on the line:

Address	Instruction	Description
0000	C1000C
0003	18
0004	F1000B
0007	51000B
000A	00
000B	00
000C	FFDC

1. Submit the code with comments describing each line.
2. What is the output of the program?
3. The instruction at address 0003 is a unary instruction. What does that mean?
4. What is the instruction at 0003 doing? Give the binary value of the accumulator before and after the command.
