Maximum of Absolute Value Expression

arraymath

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

2 <= arr1.length == arr2.length <= 40000

-10^6 <= arr1[i], arr2[i] <= 10^6
