Suppose you want to make a random 9 digit number, using every number from 1 to 9 exactly once. You have a process called random(top) that gives a random number up to top (if top was 5, it would give random numbers from 1 to 5)

a) How could you do this?

b) If top couldn't be more than 9, how could you do this using random(top) only 9 times (or less)?

(In reply to re(2): Words too! by Charlie)

The reason I gave random as a given is because it can be done, and would just complicate the problem's idea :)

How to make a random number could be another problem.
