Write a MARIE subroutine that will multiply two numbers by using repeated addition. For example, to multiply 2 x 8, the program would add 8 to itself twice (if the larger of the two numbers is chosen to be added to itself, the subroutine will run more quickly). Then, write a MARIE program to evaluate the expression A x B + C x D using your function. Your program should get the values from A, B, C, and D from input and display the result.
