Why don't you hand execute it on an example, like cinits [1,2,3]?
cinits [1,2,3] = cinits (1:2:3:[]) =
[] : map (1:) (cinits (2:3:[]) =
[] : map (1:) ([] : map (2:) (cinits (3:[])) =

Hello,
I can hardly imagine how the following code works:
cinits :: [a] -> [[a]] cinits [] = [[]] cinits (x:xs) = [] : map (x:) (cinits xs)
can someone give me a good explaination?
(I understand it a bit, but it's really hard for me to figure out how a map in a map function works.)
Thank you for your time,
