There are only magic squares in test cases, however the problem doesn't specify a type of the matrix.

You should definitely strengthen the test suite. Lots of solutions rely on both diagonals being the same, even though this is not a property of the stated problem.

The "antidiagonal" is cooler sounding than "second diagonal"
