LeetCode ProblemSum of Imbalance Numbers of All Subarrays
The imbalance number of a 0-indexed integer array arr of length n is defined as the number of indices in sarr = sorted(arr) such that: Here, sorted(arr) is the function that returns the sorted version of arr. Given a 0-indexed integer array nums, return the sum of imbalance numbers of all its subarrays. A subarray is a contiguous non-empty sequence of elements within an array.
