Sum of all absolute values in two arrays
Difference between en1 and en2, changed 45 character(s)
Given two arrays A and B of size N. Let's take A={4,2,8} AND B={2,7,3}.↵
All possible absolute values are 1: |4-2|+|4-7|+|4-3|=6 ; 2: |2-2|+|2-7|+|2-3|=6 ; 3: |8-2|+|8-7|+|8-3|=12; Sum of all these is 6+6+12=24;↵
↵
Constraints : 1<=N<=10^5  ,  |Ai|,|Bi|<=10^6, so Ai,Bi can be negative↵
