Problem: Count Subarrays With Score Less Than K

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 = 2424.

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:

  • 1≤1 \leq nums.length ≤103\leq 10^{3}

  • 1≤1 \leq nums[i] ≤103\leq 10^{3}

  • 1≤1 \leq k ≤105\leq 10^{5}
