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