Understanding the Sum of Absolute Differences in a Sorted Array Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given an integer array nums sorted in non-decreasing order. Build and return an integer array result with the same length as nums such that result[i] is equal to the summation of absolute differences between nums[i] and all the other elements in the array. In other words, result[i] is equal to sum(|nums[i]-nums[j]|) where 0 <= j < nums.length and j != i (0-indexed).

Examples
nums = [2,3,5][4,3,5]Assuming the arrays are 0-indexed, then result[0] = |2-2| + |2-3| + |2-5| = 0 + 1 + 3 = 4, result[1] = |3-2| + |3-3| + |3-5| = 1 + 0 + 2 = 3, result[2] = |5-2| + |5-3| + |5-5| = 3 + 2 + 0 = 5.
nums = [1,4,6,8,10][24,15,13,15,21]Constraints
2 <= nums.length <= 1051 <= nums[i] <= nums[i + 1] <= 104How Interview Coder Helps with Leetcode Problems
