I've improved grammar in this problem and updated it with a test case ensuring that the det() function is not used. Rescoring of previous answers will take time to propagate, though
I also modified the test suite to check for sums of absolute errors under a threshold value rather than isequal(), since that can fail when the answer isn't composed purely of integers.
I see you! :)
