Solution: Range Sum of Sorted Subarray Sums
Discover how to solve the range sum of sorted subarray sums problem by applying binary search and sliding window techniques. This lesson guides you through optimizing brute-force methods to handle large inputs efficiently, helping you identify subarray sum thresholds and dynamically compute required sums. Understand the algorithm's time and space complexity and implement an efficient solution for 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
