Move letters

Logic Level 2

You have 2017 cards numbered \(1, 2, 3, \ldots, 2017\), as shown above. In each move, you can swap two adjacent cards.

What is the minimum number of moves required for the above cards to be arranged backwards as \(2017, 2016, \ldots, 2, 1\)?


As an explicit example, if you started with four cards arranged as 1234, in one move you could go to 2134, 1324, or 1243 only.
