@Nikolaos [5 5 5] can make a triangle, but not a *right* triangle (with one 90-degree angle). See the Wikipedia page definition.

No, the trick is actually fairly poor coding practice

It's difficult to give much of a hint without giving away the answer. The key is that your function needs to be able to accept ANY input.

There is a nifty trick for reducing what seems like the shortest possible solution. I don't really want to just state the trick, as it is fun to learn or discover on your own. If you can't figure it out, I suggest that you submit a simple problem to Cody, and look at the solutions. (They will all be viewable to you, as the problem submitter.) Someone will use the trick, almost certainly.

Although MATLAB does create a 2x2 matrix as an output from magic(2), that output is not a magic square.

Added this check. (I messed it up a bit the first time I tried to do it, so sorry for some interim weirdness.)

Good suggestion. I've added a couple more tests to the suite, including one that has three columns in the logical mask.

@Sumit, you are probably using a function from a toolbox (e.g. statistics toolbox) that is not available to Cody.

The MATLAB command magic(2), although it does produce output, is not a magic square, according to the definition. (There is no 2x2 magic square.)

I was not notified about some of the older comments, so was unaware of some of the weaknesses of the test suite, and the "gamed" solutions. I have substantially improved the test suite.

I somehow Alfonso's older comment until I saw Tom's newer one. Alfonso: I've added a non-sorted test sample, and had the problem rescored. Tom: 1 is neither prime nor composite. I've added instructions on how to handle that.
