Solution: Count Subarrays With Score Less Than K

Explore how to efficiently count the number of subarrays whose score is less than a given threshold k by using the sliding window technique. Understand how to maintain a running sum with two pointers to optimize performance and avoid checking every subarray individually. By the end of this lesson, you'll implement a linear time solution to solve this common coding interview problem.

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] ...
