Question 4: Using only the two following instructions, and the provided memory & register locations, move a value from memoryA to memoryB:

"move" instruction Syntax: "move memoryX, register#" Copies a value from register# to memoryX (where register# and memoryX refer to any register or memory location) eg: if register1 = 3, then "move memoryA, register1" results in register1 = 3, memoryA = 3

"subtract" instruction Syntax: "subtract register#, memoryX" Subtracts the number in memoryX from the number in register# and stores the value in register# (where register# and memoryX refer to any register or memory location) eg: if register1 = 3, memoryA = 2 then "subtract register1, memoryA" results in register1 = 1, memoryA = 2

registers: register1 register2

memory locations: memoryA memoryB
