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.
\n\n\n
Example 1:
\n\n\nInput: nums = [2,6,4,8,10,9,15]\nOutput: 5\nExplanation: You need to sort [6, 4, 8, 10, 9] in ascending order to make the whole array sorted in ascending order.\n\n\n
Example 2:
\n\n\nInput: nums = [1,2,3,4]\nOutput: 0\n\n\n
Example 3:
\n\n\nInput: nums = [1]\nOutput: 0\n\n\n
\n
Constraints:
\n\n1 <= nums.length <= 104-105 <= nums[i] <= 105\nFollow up: Can you solve it in
