Solution: Range Sum of Sorted Subarray Sums
Explore how to compute the sum of elements in a sorted array of subarray sums within given indices by applying binary search and sliding window methods. Understand optimizing brute-force approaches to handle large data efficiently without explicit storage, using modular arithmetic to manage overflow.
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
