You are given an array of integers nums of length n and a positive integer k.
The power of an array is defined as:
\n\nYou need to find the power of all subarrays of nums of size k.
Return an integer array results of size n - k + 1, where results[i] is the power of nums[i..(i + k - 1)].
\n
Example 1:
\n\nInput: nums = [1,2,3,4,3,2,5], k = 3
\n\nOutput: [3,4,-1,-1,-1]
\n\nExplanation:
\n\nThere are 5 subarrays of nums of size 3:
[1, 2, 3] with the maximum element 3.[2, 3, 4] with the maximum element 4.[3, 4, 3] whose elements are not consecutive.[4, 3, 2] whose elements are not sorted.[3, 2, 5] whose elements are not consecutive.Example 2:
\n\nInput: nums = [2,2,2,2,2], k = 4
\n\nOutput: [-1,-1]
\nExample 3:
\n\nInput: nums = [3,2,3,2,3,2], k = 2
\n\nOutput: [-1,3,-1,3,-1]
\n\n
Constraints:
\n\n1 <= n == nums.length <= 1051 <= nums[i] <= 1061 <= k <= ndp[i] denote the length of the longest subarray ending at index i that has consecutive and sorted elements.",
"Use a TreeMap with a sliding window to check if there are k elements in the subarray ending at index i.",
"If TreeMap has less than k elements and dp[i] < k, the subarray has power equal to -1.",
"Is it possible to achieve O(nums.length) using a Stack?"
