Hi Antoine,
The first Int field is a unique index, beginning at 1 and increasing by 1 for each unique Node.
Then you could use that for indexing, assuming the Ord instance matches. range (MyNode x _ _ _, MyNode y _ _ _) = [x .. y] index (MyNode x _ _ _, MyNode y _ _ _) (MyNode z _ _ _) | x <= z && z <= y = z-x | otherwise = error ("Index out of range: " ++ show z) etc.
The second [Int] field is just a list of random numbers associated with that node.
