Thank you very much, sir!

The test is ok, check the two last columns.

[1, 3, 2, 5, 7, 9, 4, 6, 8]
[4, 9, 8, 2, 6, 1, 3, 7, 5]
[7, 5, 6, 3, 8, 4, 2, 1, 9]
[6, 4, 3, 1, 5, 8, 7, 9, 2]
[5, 2, 1, 7, 9, 3, 8, 4, 6]
[9, 8, 7, 4, 2, 6, 5, 3, 1]
[2, 1, 4, 9, 3, 5, 6, 8, 7]
[3, 6, 5, 8, 1, 7, 9, 2, 4]
[8, 7, 9, 6, 4, 2, 1, 3, 5]

I think this test is supposed to be True, but the answer is False at the moment.
