Solution: Find the Distance Value Between Two Arrays

Explore how to calculate the distance value between two arrays by sorting one array and applying binary search on the other. Understand the step-by-step approach to efficiently determine elements in one array that meet a specific distance condition relative to the other, focusing on optimizing 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]| <= d.

Constraints:

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

  • ...
