[Haskell-beginners] Re: [Haskell-begin] Maximum of a List?

First of all, thanks for pointing out the old ghci. I had installed it on a lab computer by just googling 'ghci windows' and that was what came up. My home machine has the newest one, and is also considerably beefier hardware-wise. I think you're onto something with the Int/Integer thing....when using a type signature of "Integer", "f 1 113383" gives "248" immediately. Compiling and running the code with "Integer" types on my home machine yields "525".... which Euler says isn't the right answer? Also, on the strictness annotations: Do you put them in the type declaration? Or in the pattern match on the lhs of the declaration?
