Solution: Find the Distance Value Between Two Arrays

Understand how to compute the distance value between two arrays by sorting one array and applying binary search to find closest elements. This lesson guides you through implementing an efficient algorithm that avoids brute-force checks, balances time and space complexity, and leverages sorting and search patterns to solve complex interview questions.

We'll cover the following...

Statement

You are given two integer arrays, arr1 and arr2, along with an integer d. Your task is to find and return the distance value between these arrays.

Note: The distance value is defined as the count of elements in arr1 for which there is no element in arr2 such that ∣arr1[i]−arr2[j]∣<=|arr1[i]-arr2[j]| <= ...
