So the array is “12 -3 10 0”
if I divide and arrange the elements in the order:
A = 10,12
B = 0,-3
Diff between these array is : abs(10-0) + abs(12 - (-3)) = 25
if I divide and arrange the elements in the order:
A = 0,10
B = -3,12
Diff between these array is : abs(0 - (-3)) + abs(10 - 12) = 5
So, Minimum difference is 5 and max. is 25.
