# LeetCode – Arrays – Find the Distance Value Between Two Arrays

#### ByKnight Coderz

Apr 7, 2020

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```
``class Solution {    public int findTheDistanceValue(int[] arr1, int[] arr2, int d) {       int distance = 0;       for(int i=0;i<arr1.length;i++){           List<Boolean> boundaryList = new ArrayList<Boolean>();           for(int j=0;j<arr2.length;j++){               if(Math.abs(arr1[i]-arr2[j]) <= d) boundaryList.add(true);           }           if(boundaryList.size() == 0) distance++;       }        return distance;    }}``
