Description

### 问题描述

环形公交路线上有 n 个站,按次序从 0 到 n - 1 进行编号。我们已知每一对相邻公交站之间的距离,distance[i] 表示编号为 i 的车站和编号为 (i + 1) % n 的车站之间的距离。

环线上的公交车都可以按顺时针和逆时针的方向行驶。

返回乘客从出发点 start 到目的地 destination 之间的最短距离。

示例 1:

输入:distance = [1,2,3,4], start = 0, destination = 1
输出:1
解释:公交站 0 和 1 之间的距离是 1 或 9,最小值是 1。
 

示例 2:

输入:distance = [1,2,3,4], start = 0, destination = 2
输出:3
解释:公交站 0 和 2 之间的距离是 3 或 7,最小值是 3。
 

示例 3:

输入:distance = [1,2,3,4], start = 0, destination = 3
输出:4
解释:公交站 0 和 3 之间的距离是 6 或 4,最小值是 4。
 

提示:

1 <= n <= 10^4
distance.length == n
0 <= start, destination < n
0 <= distance[i] <= 10^4
