 * 那結果是15 (departure[1] + arrival[3] = 8 + 7 = 15)

// sliding[B >: A](size: Int, step: Int = 1): GroupedIterator[B]
// Returns an iterator which presents a "sliding window" view of another iterator. 
// The first argument is the window size, and the second is how far to advance the window on each iteration; defaults to 1. 
// Example usages:

// Returns List(List(1, 2, 3), List(2, 3, 4), List(3, 4, 5))
(1 to 5).iterator.sliding(3).toList
// Returns List(List(1, 2, 3, 4), List(4, 5))
(1 to 5).iterator.sliding(4, 3).toList
// Returns List(List(1, 2, 3, 4))
