Hello,
First, and forgive me if I'm making unwarranted assumptions, but

Second: div, mod, reverse, and the unfoldr function from Data.List
will do what you want.

Is some kind of collection of object with different types in Haskell
exist? Except the tuples, which have fixed length.
I find this
* Tuples heterogeneous, lists homogeneous.
* Tuples have a fixed length, or at least their length is encoded in
their type. That is, two tuples with

Hello,
i'd like to write a function that given a list like [1,2,3,4...]
returns a list of couple where the first element is the corresponding
element of the string, and the second is the sum of the previous
elements.
An example:
input: [1,2,3,4]
output:

So, this algorithm should work fine for you

buildCouples (x:xs) s = [(x,s)] ++ (buildCouples xs (x+s)).
Please ignore the . at the end, it is a typo :( Sorry again

But I need something which is heterogeneous and non-fixed length. I'm
used do Java, and this switch to functional languages is very strange to
me. So, to be clear, I need something like

Hi Valentin
Please, take a look at the Haskell Wiki page for debugging.

You will find that thanks to Neil Mitchell there is a Windows version
of Hat available. Perhaps you can add your experiences with it if it
