Maximum Absolute Difference
You are given an array of N integers, A1, A2 , , AN. Return maximum value of f(i, j) for all 1 ≤ i, j ≤ N. f(i, j) is defined as |A[i] - A[j]| + |i - j|, where |x| denotes absolute value of x. For example, A=[1, 3, -1] f(1, 1) = f(2, ... 2, 3) = f(3, 2) = |3 - (-1)| + |2 - 3| = 5 So, we return 5. Source - https://www.interviewbit.com/problems/maximum-absolute-difference/
