1385. Find the Distance Value Between Two Arrays

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.

+ +

 

+

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
