Hi, I'm going through the first chapters of the Real World Haskell book, so I'm still a complete newbie, but today I was hoping I could solve the following function in Haskell, for large numbers (n > 108) f(n) = max(n,f(n/2)+f(n/3)+f(n/4)) I've seen examples of memoization in Haskell to solve fibonacci numbers, which involved computing (lazily) all the fibonacci numbers up to the required n. But in this case, for a given n, we only need to compute very few intermediate results. How could one go about solving this efficiently with Haskell?
