Partition Array into Disjoint Intervals Given an integer array nums, partition it into two (contiguous) subarrays left and right so that:

  • Every element in left is less than or equal to every element in right.
  • left and right are non-empty.
  • left has the smallest possible size.

Return the length of left after such a partitioning.

Test cases are generated such that partitioning exists.

Example 1:

Input: nums = [5,0,3,8,6]
Output: 3
Explanation: left = [5,0,3], right = [8,6]

Example 2:

Input: nums = [1,1,1,0,6,12]
Output: 4
Explanation: left = [1,1,1,0], right = [6,12]

Constraints:

  • 2 <= nums.length <= 105
  • 0 <= nums[i] <= 106
  • There is at least one valid answer for the given input.
