IS 139 Assignment 2 Instructions ● Assignment should be done by a group of maximum 2 people ● For each of the following questions write the MARIE program, assemble it and test it using the provided MARIE simulator. ● Submit a zip file containing the MARIE assembly file(s) for each question Questions 1. Write a MARIE program using a loop that multiplies two positive numbers by using repeated addition. For example, to multiply 3 x 5, the program would add 3 five times, or 3 + 3 + 3 + 3 + 3 2. Write a MARIE assembly program to accomplish the following task if x == y then x = x * 2; else y = y x; where x & y can be any value. e.g. x = 15 & y = 20 3. Write a MARIE assembly program that adds the first ten numbers from 1 to 10 i.e. 1 + 2 + 3 + 4 + 5 + 6 +7 + 8 + 9 + 10 4.
