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 4.14, 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.
