Solution: Count Subarrays With Score Less Than K
Explore the sliding window method to efficiently count the number of subarrays in an array whose score is less than a given integer k. Understand how to use two pointers and a running sum to avoid checking every subarray individually, reducing time complexity to linear.

Statement
An array score is defined as the sum of the array elements multiplied by its length. For example, if the array is
Given an array of positive integers, nums, and a positive integer k, count and return the number of non-empty subarrays of nums whose score is strictly less than k.
Note: A subarray is a contiguous sequence of elements within an array.
Constraints:
