Maximum Score of a Good Subarray
You are given an array of integers nums (0-indexed) and an integer k.
The score of a subarray (i, j) is defined as min(nums[i], nums[i+1], ..., nums[j]) * (j - i + 1). A good subarray is a subarray where i <= k <= j.
Return the maximum possible score of a good subarray.
Example 1
Input
nums = [1,4,3,7,4,5], k = 3Output
15The optimal subarray is (1, 5) with a score of min(4,3,7,4,5) * (5-1+1) = 3 * 5 = 15.
Example 2
Input
nums = [5,5,4,5,4,1,1,1], k = 0Output
20The optimal subarray is (0, 4) with a score of min(5,5,4,5,4) * (4-0+1) = 4 * 5 = 20.
Constraints
- 1 <= nums.length <= 10^5
- 1 <= nums[i] <= 2 * 10^4
- 0 <= k < nums.length
