Haskell: Change a list of 100 numbers to 10 lists of 10 numbers?

Question

In Haskell, how does one change a list of x numbers into n lists of n numbers?

The first sublist would have numbers first to tenth, second list 11th to 20th...

myFunction :: [Int] -> [[Int]]

Answer 1

There is the chunksOf function in Data.List.Split:

chunksOf 2 [0, 1, 2, 3] -- [[0, 1], [2, 3]]

Alternatively, we already have splitAt in prelude, with which chunksOf can be implemented with ease:

chunksOf :: Int -> [a] -> [[a]]
chunksOf n [] = []
chunksOf n xs = let (as, bs) = splitAt n xs in as : chunksOf n bs
