Reverse engineer the following Marie code, i.e. translate it into high level language such as C++.

/ Example 4.2 ORG 100 If, Load X /Load the first value Subt Y /Subtract the value of Y, store result in AC Skipcond 400 /If AC=0, skip the next instruction Jump Else /Jump to Else part if AC is not equal to 0 Then, Load X /Reload X so it can be doubled Add X /Double X Store X /Store the new value Jump Endif /Skip over the false, or else, part to end of if Else, Load Y /Start the else part by loading Y Subt X /Subtract X from Y Store Y /Store Y-X in Y Endif, Halt /Terminate program (it doesn't do much!) X, Dec 12 /Load the loop control variable Y, Dec 20 /Subtract one from the loop control variable END
