Solution: Range Sum of Sorted Subarray Sums
Understand how to find the sum of elements in a sorted array of subarray sums between given indices by applying binary search and sliding window methods. This lesson teaches an optimized solution over brute force, focusing on efficient calculation without generating all subarrays explicitly.
We'll cover the following...
Statement
You are given an integer array nums containing left and right. Calculate the sum of its elements for every non-empty continuous subarray of nums. Collect these sums into a new array and sort it in nondecreasing order. This will result in a new array of size
Your task is to return the sum of the elements in this sorted array from the index left to right (inclusive with 1-based indexing).
Note: As the result can be large, return the sum modulo
