Solution: Range Sum of Sorted Subarray Sums
Explore how to efficiently compute the sum of sorted subarray sums between given indices in an integer array. Learn to apply binary search combined with sliding window techniques to avoid brute-force methods. Understand how to optimize the process for large arrays by counting and summing subarrays dynamically, ensuring efficient time and space usage.
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
