Range Sum of Sorted Subarray Sums

Explore how to calculate the sum of continuous subarray sums from a sorted array segment using efficient sorting and indexing techniques. Understand handling large sums with modulo arithmetic and practice implementing solutions that operate within given constraints.

We'll cover the following...

Statement

You are given an integer array nums containing nn positive integers along with 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 n×(n+1)/2n \times (n + 1) /2 ...
