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

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 ...
