Only works because test suite isn't extensive enough. Wouldn't work with a = [1 0 1; 0 0 0; 0 1 0], for example.

This solution has a minor bug, but it fortunately passed the test suite. :-)

It's supposed to be a n-QUEENS checker, not an n-KINGS checker. This solution wouldn't work with a = [1 0 1; 0 0 0; 0 1 0], for example.

Thanks yurenchu! I added your proposed test point to the tests.

test suite needs additional samples that fail due to diagonal movements (e.g. [1,0;0,1])

I added this test. Rescoring now. Thanks for the suggestion.
