Given an integer array nums, you need to find one continuous subarray such that if you only sort this subarray in non-decreasing order, then the whole array will be sorted in non-decreasing order.
Return the shortest such subarray and output its length.
Examples
Example 1
Input: nums = [2,6,4,8,10,9,15]
Output: 5
Explanation: You need to sort [6, 4, 8, 10, 9] in ascending order to make the whole array sorted in ascending order.
Example 2
Input: nums = [1,2,3,4]
Output: 0
Example 3
Input: nums = [1]
Output: 0
Constraints
1 <= nums.length <= 104
-105 <= nums[i] <= 105
