Array
Sliding Window
You are given an array of integers nums of length n and a positive integer k.
The power of an array is defined as:
You 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)].
Examples
Example 1
Input: nums = [1,2,3,4,3,2,5], k = 3
Output: [3,4,-1,-1,-1]
Explanation:
There are 5 subarrays of nums of size 3:
Example 2
Input: nums = [2,2,2,2,2], k = 4
Output: [-1,-1]
Example 3
Input: nums = [3,2,3,2,3,2], k = 2
Output: [-1,3,-1,3,-1]
Constraints
1 <= n == nums.length <= 105
1 <= nums[i] <= 106
1 <= k <= n
