Solution: Range Sum of Sorted Subarray Sums
Understand how to calculate the sum of sorted subarray sums between given indices efficiently by applying binary search combined with sliding window optimization. This lesson helps you avoid brute-force methods, enhancing your problem-solving skills for array manipulation and sorting challenges typically encountered in coding interviews.
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
