Given an array nums of n integers, your task is to find the maximum value of k for which there exist two adjacent subarrays of length k each, such that both subarrays are strictly increasing. Specifically, check if there are two subarrays of length k starting at indices a and b (a < b), where:

Return the maximum possible value of k.

A subarray is a contiguous non-empty sequence of elements within an array.

Example 1

Input: nums = [2,5,7,8,9,2,3,4,3,1]

Output: 3

Example 2

Input: nums = [1,2,3,4,4,4,4,5,6,7]

Output: 2

Constraints

  • 2 <= nums.length <= 2 * 10^5
  • -10^9 <= nums[i] <= 10^9
