Solution: Count Subarrays With Score Less Than K

Explore the sliding window technique to efficiently count all subarrays whose score, calculated as the sum of elements times the subarray length, is less than a given value k. This lesson teaches how to maintain a dynamic window with two pointers and a running sum to avoid inefficient recalculations, enabling you to solve the problem with O(n) time complexity in JavaScript.

Statement

An array score is defined as the sum of the array elements multiplied by its length. For example, if the array is [2,1,5][2, 1, 5] ...
