((equal? s (car lis)) Hs)

(else (y s (cdr lis)))

) )

3. What does the following Scheme function do?

4. Write a Scheme function that computes the volume of a sphere, given its radius.

5.  Write a Scheme function that takes a simple list of numbers as a parameter A and B and returns a list with the largest and smallest numbers in the input list.

6. Write a Scheme function that takes a list as a parameter and returns a list identical to the parameter except the last element has been deleted.
