This is exercise 20 in chapter 2 - but this time i would need to Repeat Exercise 20 in Chapter 2 , using the ADT list to implement the function f (n).

Consider the following recurrence relation:

F (1) = 1; f (2) = 1; f(3) =1; f(4) =3; f(5) = 5;

f (n) = f( n -1 ) + 3 x f(n-5) for all n > 5

Compute f(n ) for the following values of n : 6, 7, 12, 15.

If you were careful, rather than computing f (15) from scratch (the way a recursive C++ function would compute it), you would have computed f (6), then f (7), then f(8), and so on up to f(15), recording the values as you computed them. This ordering would have saved you the effort of ever computing the same value more than once. (Recall the iterative version of the rabbit function discussed at the end of this chapter.) Note that during the computation
