/**
 * 1385. Find the Distance Value Between Two Arrays
 *
 * 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.
 *
 * Example 1:
 * Input: arr1 = [4,5,8], arr2 = [10,9,1,8], d = 2
 * Output: 2
 * Explanation:
 * For arr1[0]=4 we have:
 * |4-10|=6 > d=2
 * |4-9|=5 > d=2
 * |4-1|=3 > d=2
 * |4-8|=4 > d=2
 * For arr1[1]=5 we have:
 * |5-10|=5 > d=2
 * |5-9|=4 > d=2
 * |5-1|=4 > d=2
 * |5-8|=3 > d=2
 * For arr1[2]=8 we have:
 * |8-10|=2 <= d=2
 * |8-9|=1 <= d=2
 * |8-1|=7 > d=2
 * |8-8|=0 <= d=2
 *
 * Example 2:
 * Input: arr1 = [1,4,2,3], arr2 = [-4,-3,6,10,20,30], d = 3
 * Output: 2
 *
 * Example 3:
 * Input: arr1 = [2,1,100,3], arr2 = [-5,-2,10,-3,7], d = 6
 * Output: 1
 *
 * Constraints:
 * 1 <= arr1.length, arr2.length <= 500
 * -10^3 <= arr1[i], arr2[j] <= 10^3
 * 0 <= d <= 100
