LeetCode ProblemMaximum 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.
