Sliding Window Algorithm with Example

A sliding window is a sublist that runs over an underlying collection. I.e., if you have an array like

[a b c d e f g h]

a sliding window of size 3 would run over it like

[a b c]
  [b c d]
    [c d e]
      [d e f]
        [e f g]
          [f g h]

This is useful if you for instance want to create a set of all adjacent pairs, or generate N-grams etc.
