Solution: Count Subarrays With Score Less Than K

Understand how to apply the sliding window technique to efficiently count all non-empty subarrays in an array whose scores, defined as the sum of elements multiplied by their length, are less than a given value k. Learn to use two pointers and a running sum to track and adjust subarrays in linear time, avoiding brute force. This lesson helps you master problem-solving strategies for array subproblems with better performance.
