Why cannot u explain the test case?

#1

Please explain the test case.

#2

Divide the array as
A = -3 , 10
B = 0 , 12

Min Ans = abs(-3-0) + abs(10-12) = 5

======================
Now Divide array as:
A = -3 , 0
B = 10 , 12
Max Ans = abs(-3 -10) + abs(0 - 12) = 25

#3

∑ i = 1 N / 2 a b s ( A i − B i ) in the question means:
for i goes to 1 to n/2, find summation of abs(Ai - Bi)
