Question

Ashley has 100 books that she wants to give away at the rate of n books per week. Write a recursive function that represents the number of books Ashley has at any time.
The recursive function that gives the number of books Ashley has at any time is

Answer 1

Let B(w) be the number of books that Ashley has in week w and specify w >= 0.

A recursive function has two parts:

1. A simple base case (or cases)—a terminating scenario that does not use recursion to produce an answer

2. A set of rules that reduce all other cases toward the base case

So, for Ashley, the number of books at any time is:

1. If w = 0 then B(w) = 100

2. If w > 0 then B(w) = MAX( B(w-1) – n, 0 ) [note: B(w) cannot be negative]
