Using the MARIE computer assembly language, write a program that computes the following expression: z $=$ a $*$ b$,$ where a and b are positive numbers. The computer will read in the input values a$,$ and b 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.
