I thought someone had done that recently as a graduate thesis.

Sometimes it is interesting to approach things from a different
perspective. The goofyness below will have been useful if it interests
you in point-free programming. And anyway, I sure had a good time
writing it...
I am composing several common Haskell idioms:

The algorithm I would use:
Treat the problem as a directed graph of 1 million vertices where each
vertex has at most 1 outgoing edge. Each vertex is labeled with a
number N(v).
For each vertex v, if sum(divisors(N(v))) <= 1 million, that vertex has an
outgoing edge to vertex v', where N(v') == s

After much progress and learning, I'm stuck again trying to get happs to
compile under ghc 6.7. (Hoping that running happs under the new ghc
debugger will help me understand it better.)
I was trying to compile from the "stable" 8.8 version, unzipped and with
just a few modifications. (see attac

Wait, is this an exam for a class you're taking? Or just a problem from an

It looks like it works, but you can get a better version by changing
the last line:

I would implement this using direct recursion. As a starting point,

Hello,
I just came across with this question on the exam and can not think of
implementing it.
mapPair :: (a -> a -> a) -> [a] -> [a]
such that mapPairs f [x1, x2, x3, x4...] = [f x1 x2, f x3 x4,...]
and if the list contains an odd number of elements, the last one is kept
unchanged, for exampl

I'm trying to compile regex-posix on ghc 6.7. (Ultimate goal: happs on

First, I patched by changing the cabal file to be compatible with the new
libraries broken out of base. I also had to add HsRegexPosixConfig.h to
