2302. Count Subarrays With Score Less Than K

The score of an array is defined as the product of its sum and its length. - For example, the score of [1, 2, 3, 4, 5] is (1 + 2 + 3 + 4 + 5) * 5 = 75. Given a positive integer array nums and an integer k, return the number of non-empty subarrays of nums whose score is strictly less than k. A subarray is a contiguous sequence of elements within an array. Example 1: Input: nums = [2,1,4,3,5]
