+-- 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.
