Solution: Find the Distance Value Between Two Arrays

Explore how to calculate the distance value between two arrays by sorting one array and using binary search to efficiently compare elements. This lesson helps you implement a search-based pattern to solve the problem with optimal time complexity and understand how sorting enhances binary search applications in array comparisons.

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]| <= ...
