1. text provides an example of the execution of a simple MARIE program. For this problem, you are to complete a similar example for a different program. In particular, for the MARIE program given below, you are to complete the equivalent of Figure, but for the program below. You do not need to show how the "Halt" instruction is executed. Specify values in PC, IR, MAR, MBR, and AC in hexadecimal. A template for your answer is provided as a Microsoft Word file that is included with this assignment on Scholar. You are to incorporate your answer for this problem into your submission for the homework assignment so that you submit only one PDF file for the entire assignment.

The program is as follows. Note that this table is the equivalent of Table, only for a different program.

Hex Address	Instruction	Binary Contents of Memory Address	Hex Contents of Memory
100	Load  105	0001 0001 0000 0101	1105
101	Subt  104	0100 0001 0000 0100	4104
102	Store 104	0010 0001 0000 0100	2104
103	Halt	0111 0000 0000 0000	7000
104	00A3	0000 0000 1010 0011	00A3
105	00F3	0000 0000 1111 0011	00F3
