Solution: Find the Distance Value Between Two Arrays

Understand how to calculate the distance value between two arrays by sorting one array and performing binary search on the other. This lesson helps you apply the sort and search pattern to improve efficiency and avoid brute-force methods while solving coding interview problems.

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]| <= ...
