1184. Distance Between Bus Stops

https://leetcode.com/problems/distance-between-bus-stops

Description

A bus has n stops numbered from 0 to n - 1 that form a circle. We know the distance between all pairs of neighboring stops where distance[i] is the distance between the stops number i and (i + 1) % n.

The bus goes along both directions i.e. clockwise and counterclockwise.

Return the shortest distance between the given start and destination stops.

Example 1:


**Input:** distance = [1,2,3,4], start = 0, destination = 1
**Output:** 1
**Explanation:** Distance between 0 and 1 is 1 or 9, minimum is 1.

Example 2:


**Input:** distance = [1,2,3,4], start = 0, destination = 2
**Output:** 3
**Explanation:** Distance between 0 and 2 is 3 or 7, minimum is 3.

Example 3:


**Input:** distance = [1,2,3,4], start = 0, destination = 3
**Output:** 4
**Explanation:** Distance between 0 and 3 is 6 or 4, minimum is 4.

Constraints:

  • 1 <= n <= 10^4

  • distance.length == n

  • 0 <= start, destination < n

  • 0 <= distance[i] <= 10^4
