Solution: Find the Distance Value Between Two Arrays

Explore how to find the distance value between two arrays by sorting one array and applying binary search to efficiently evaluate element differences. This lesson helps you implement optimized solutions using sorting and search patterns, improving your ability to handle similar 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]| <= d.

Constraints:

  • 1<=1 <= arr1.length, arr2.length <=500 <= 500

  • ...
