    Test/Attempt is not working:
    Expected 'false' on input of
    [ [ 1, 2, 3, 4, 5, 6, 7, 8, 9 ],
    [ 2, 3, 1, 5, 6, 4, 8, 9, 7 ],
    [ 3, 1, 2, 6, 4, 5, 9, 7, 8 ],
    [ 4, 5, 6, 7, 8, 9, 1, 2, 3 ],
    [ 5, 6, 4, 8, 9, 7, 2, 3, 1 ],
    [ 6, 4, 5, 9, 7, 8, 3, 1, 2 ],
    [ 7, 8, 9, 1, 2, 3, 4, 5, 6 ],
    [ 8, 9, 7, 2, 3, 1, 5, 6, 4 ],
    [ 9, 7, 8, 3, 1, 2, 6, 4, 5 ] ]
