need to add non-sorted test samples (e.g. [3,2,1])?
It looks like 1 is being incorrectly sorted as a composite number in the testcases.
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.
I had assumed that "in order" meant "in the order provided". If that were the case, then [5 1 3 2 4] would return [5 3 2 1 4]. Maybe you could say you want them sorted rather than in order.
Maybe a test case with a non-sorted input would be nice
