// Create a program that multiplies R0 & R1 and puts the result in R2
// Algorithm is based on repetetive action.

//

// okay let's go.

// Get R0
// Create a loop based on the number of R0. I.e loop 10 times if R0 is 10.
// Everytime around sum of R2 should be incremented by R1
// Need variable @i which is the index. If that reaches 0. Loop end

    // Variables
    @i
    M=1
    @R2
    M=0
    // Check if loop is needed.
    @R0
    D=M
    @END // Jump to End if R0 is 0. Nothing to add.
