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
