1 -- Hi everyone!
|
|
|
2 -- Could please someone explain me an output of the function:
|
|
|
3
|
|
|
4 splitEvery n list = first : ( splitEvery n rest )
|
|
|
5 where (first, rest) = splitAt n list
|
|
|
6
|
|
|
7 -- it returns a lis of lists splitEvery :: Int -> [a] -> [[a]]
|
|
|
8 -- But I don't understand how it works, why it returns list of lists.
|
|
|
9 -- splitAt returns TUPLE and "first" is somehow joined to it. |
