/**
 * 1385. Find the Distance Value Between Two Arrays
 * https://leetcode.com/problems/find-the-distance-value-between-two-arrays/
 * Difficulty: Easy
 *
 * Given two integer arrays arr1 and arr2, and the integer d, return the distance value between
 * the two arrays.
 *
 * The distance value is defined as the number of elements arr1[i] such that there is not any
 * element arr2[j] where |arr1[i]-arr2[j]| <= d.
