Hi there! I have already written the code for this in a previous assignment.... but this new assignment includes the calculation of inputs that include negative numbers or 0 (circled it in red). Not quite sure how to go about this. My code is there as well, so feel free to simply edit it to accommodate instructions. Thanks a bunch!

Using the MARIE computer assembly language, write a program that computes the following expression: z=abc. The computer will read in the input values a,b, and c from the keyboard and the final result (z) have to be displayed. In addition, every time an input value is read in, it must be displayed on the screen. Remember that the instruction set does not have an instruction to execute multiplication. Note: If any of the input values a,b, and c is a negative numbers or a zero, then the result printed should be " 0 ". Otherwise, the result of the multiplication must be printed. The program must be tested on MARIE simulator. On Webcourses you will find the MARIE folder with all the necessary documents on MARIE: 1) How to download the MARIA simulator 2) A guide to the MARIE simulator environment. 3) A presentation to understand MARIE
