Solution: Find the Distance Value Between Two Arrays

Explore how to find the distance value between two arrays by sorting one array and using binary search to check if elements from the other array meet a defined difference condition. Understand how this approach improves efficiency over brute-force methods and analyze its time and space complexity.

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]| <= ...
