Hi, My name is Michael. I'm new to Haskell. I'm working through The Craft of Functional Programming by Simon Thompson. I'm having problems with a few exercises from chapter 4. I will present one per post.
This one is from 4.9 Given a function f of type Int -> Int give a recursive definition of a function of type Int -> Int which on input n returns the maximum values f 0, f 1, ... , f n I defined f as follows f 0 = 0 f 1 = 44 f 2 = 5 f 9 = 8 this works except when f n > n. In that case I get an "illegal instruction" error and hugs exits. I'm pretty sure this is a logic problem. Could someone point me in the right direction so I can think about this problem correctly. Here is my code maxOverf :: Int -> Int maxOverf m | f m > m = (f m) | otherwise = (maxOverf m-1) Any hints/help/flames welcome.
