Maximum of Absolute Value Expression(LeetCode 1131):

Problem

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
