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.

No unique solution. For me it is the last solution of the permutation matrix.
For which test statement is there not a unique solution? We need to fix the test suite if there are two answers of same score.
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 ...
