# Maximum of Absolute Value Expression

Given two arrays of integers with equal lengths, return the maximum value of:

`|arr1[i] - arr1[j]| + |arr2[i] - arr2[j]| + |i - j|`

where the maximum is taken over all `0 <= i, j < arr1.length`.

**Example 1:**

```
Input: arr1 = [1,2,3,4], arr2 = [-1,4,5,6]
Output: 13
```

**Example 2:**

```
Input: arr1 = [1,-2,-5,0,10], arr2 = [0,-2,-1,-7,-4]
Output: 20
```

**Constraints:**

* `2 <= arr1.length == arr2.length <= 40000`
* `-10^6 <= arr1[i], arr2[i] <= 10^6`
