+/**
+ * 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
+ * */
