Solution: Count Subarrays With Score Less Than K

Explore how to count the number of subarrays whose score—defined as the sum of elements multiplied by the subarray length—is less than a given value k. Learn to apply the sliding window technique with two pointers to maintain a running sum and achieve an efficient O(n) time complexity solution without redundant computations.

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] ...
