Consider the following program in MARIE assembly language. Complete the table detailing the RTN for next 3 instructions only that will be executed including the content of registers PC, IR, MAR, MBR and AC in hexadecimal. Note the first instruction LOAD X is already filled. Note also that SKIPCOND instruction has no operands, therefore you can complete Fetch, decode and execute cycles only. Explain in one statement what is this program doing?
