Solution: Count Subarrays With Score Less Than K
Understand how to use the sliding window approach to count the number of contiguous subarrays whose score, defined as the sum of elements times the subarray length, is less than a given threshold k. Learn to efficiently manage two pointers and a running sum for a linear time solution, preparing you to solve similar array problems in coding interviews.
We'll cover the following...
Statement
An array score is defined as the sum of the array elements multiplied by its length. For example, if the array is
Given an array of positive integers, nums, and a positive integer k, count and return the number of non-empty subarrays of nums whose score is strictly less than k.
Note: A subarray is a contiguous sequence of elements within an array.
Constraints:
nums.length...
