Answer 1

In addition to Luigi´s answer.

3) You should think about filtering out the punctuation.

4) Another hint:

scala> val list = List(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
list: List[Int] = List(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

scala> val listOfTwoElements = list.sliding(2).toList
listOfTwoElements: List[List[Int]] = List(List(1, 2), List(2, 3), List(3, 4), List(4, 5), List(5, 6), List(6, 7), List(7, 8), List(8, 9), List(9, 10))
