functional programming - Iterating along 2 lists at the same time in haskell (without resorting to zip) -

i have 2 lists:

[[1,2],[4,5]]

and

[0, 3]

and i'd turn into

[[0,1,2],[3,4,5]]

i've created function that:

myfun xxs xs = map (\x -> (fst x):(snd x)) (zip xs xxs)

and works. still left wondering whether there might exist better way accomplish without using zip. there any?

basically want iterate along 2 lists @ same time, can't think of way in haskell without resorting zip.

thanks

use zipwith. example:

zipwith (:) [0,3] [[1,2],[4,5]]

gives:

[[0,1,2],[3,4,5]]

shell
