Im self studing Haskell with the Craft o ffunctional programmimg of Hutton.

Now I see two exercises that I do not understand what is really the purpose here.

Maybe a slight rewording of the instructions would help? (It helped me!)

The two exercises are :

4.21 Given a function f of type Integer -> Integer give a recursive definition of a
function of type Integer -> Integer which on input n returns the maximum
of the values f 0, f 1, ..., f n. [...]

 

Given:

  f :: Integer -> Integer

Define:

  g :: Integer -> Integer

  g n = ...

such that g is defined recursively. g n returns the maximum of f 0, f 1, ..., f n.
