Solution: Find the Distance Value Between Two Arrays

Understand how to find the distance value between two arrays by sorting one array and using binary search to check absolute differences. This lesson teaches efficient techniques to solve such problems with optimized time and space complexity, improving your skills with the sort and search coding pattern.

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]| <= ...
