数轴上放置了一些筹码,每个筹码的位置存在数组 chips 当中。

你可以对 任何筹码 执行下面两种操作之一(不限操作次数,0 次也可以):

将第 i 个筹码向左或者右移动 2 个单位,代价为 0。
将第 i 个筹码向左或者右移动 1 个单位,代价为 1。
最开始的时候,同一位置上也可能放着两个或者更多的筹码。

返回将所有筹码移动到同一位置(任意位置)上所需要的最小代价。

 

示例 1:

输入:chips = [1,2,3]
输出:1
解释:第二个筹码移动到位置三的代价是 1,第一个筹码移动到位置三的代价是 0,总代价为 1。
示例 2:

输入:chips = [2,2,2,3,3]
输出:2
解释:第四和第五个筹码移动到位置二的代价都是 1,所以最小总代价为 2。
 

提示:

1 <= chips.length <= 1

A short (3 point) closed linestring (rare, but does happen) throws an exception in clean-coords due to the code assuming it's a polygon.

This can also happen with a linestring that is cleaned to < 4 points. Discovered thi
