Given 4 unsorted arrays A , B , C , D of size N , find the value of

```
MAX( abs( A[ i ] - A[ j ] ) + abs( B[ i ] - B[ j ] ) + abs( C[ i ] - C[ j ] ) + abs( D[ i ] - D[ j ] ) +abs( i - j) )
```

where 0 < = i < j < N

I think this is the modified version of this : https://www.geeksforgeeks.org/maximum-value-arri-arrj-j/

But unable to solve . Help @galencolin @aryan12 @nishant403 @hetp111 @ssjgz
