2289 - Steps to Make Array Non-decreasing.

Medium

You are given a 0-indexed integer array nums. In one step, remove all elements nums[i] where nums[i - 1] > nums[i] for all 0 < i < nums.length.

Return the number of steps performed until nums becomes a non-decreasing array.

Example 1:

Input: nums = [5,3,4,4,7,3,6,11,8,5,11]

Output: 3

Explanation: The following are the steps performed:

  • Step 1: [5, 3 ,4,4,7, 3 ,6,11, 8 , 5 ,11] becomes [5,4,4,7,6,11,11]

  • Step 2: [5, 4 ,4,7, 6 ,11,11] becomes [5,4,7,11,11]

  • Step 3: [5, 4 ,7,11,11] becomes [5,7,11,11]

[5,7,11,11] is a non-decreasing array. Therefore, we return 3.

Example 2:

Input: nums = [4,5,7,7,13]

Output: 0

Explanation: nums is already a non-decreasing array. Therefore, we return 0.

Constraints:

  • 1 <= nums.length <= 105
  • 1 <= nums[i] <= 109
