Solution: Find the Distance Value Between Two Arrays

Explore how to calculate the distance value between two integer arrays by sorting one array and using binary search to efficiently compare elements. Understand the step-by-step process, including condition checks and time complexity, to master this pattern for coding interviews.

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]| <= ...
