Count Subarrays With Score Less Than K

Explore how to use the sliding window approach to count subarrays whose score, defined as the sum of elements times the length, is less than a given value k. This lesson helps you develop an efficient method to solve array problems by identifying and applying the sliding window pattern.

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], then its score is (2+1+5)×3(2 + 1 + 5) \times 3 ...
