在一條線狀的草地上，有N叢草。你可以把他視為數線上的N個數(1 <= N <= 1,000)，這些數分別在一些整數點上。
Bessie是一隻牛，從位置L出發，想要把所有這些草吃完。定義一株草”不新鮮度”是從開始到Bessie吃到該株草所過的時間。如今Bessie希望在吃到這些草的同時，吃所有草的”不新鮮度”總和可以最小。請找出最小的”不新鮮度”總和是多少。

(原文)
A long, linear field has N (1 <= N <= 1,000) clumps of grass at unique integer locations on what will be treated as a number line. Think of the clumps as points on the number line.
Bessie starts at some specified integer location L on the number line (1 <= L <= 1,000,000) and traverses the number line in the two possible directions (sometimes reversing her direction) in order to reach and eat all the clumps. She moves at a constant speed (one unit of distance in one unit of time), and eats a clump instantly
when she encounters it.
Clumps that aren't eaten for a while get stale. We say the ``staleness'' of a clump is the amount of time that elapses from when Bessie starts moving until she eats a clump. Bessie wants to minimize the total staleness of all the clumps she eats.
Find the minimum total staleness that Bessie can achieve while eating all the clumps.
