ROM is physically read-only memory. ROM is typically used in special-purpose systems where the software is set prior to manufacturing the hardware (or at least … Read more

For the simplest solution, use apply for this: (define (multiply-all lst) (apply * lst)) If you need to build the procedure from scratch, just remember that the base case (an empty list) should return 1, and the recursive step should multiply the current value using the standard solution template, like this: (define (multiply-all lst) (if … Read more
Here’s how to do what you say you want.
