Problem 534. Find best domino orientation
Given a list of pairs, find the orientation they should be placed in a line, such that the sum of the absolute values of the differences is zero.
Zero means do not invert, One means invert in the order vector.
list = [1 2 4 2 2 3
order = [0 1 1]
yields: [1 2][2 4][3 2] or: abs(2-2) + abs(4-3) or: 0 + 1 or: 1
There is a unique solution to this problem where the final score is minimized.

Sorry, it was a mistake.
The statement of the problem is incorrect: "the sum of the absolute values of the differences is zero." You want the smallest sum, but it isn't necessarily zero.
Is there any size constraint on this problem ? My solution is not getting accepted ...
