Invalid solution, really

David Young submitted a Comment to Problem 2202. Flip the bit

The test suite does not check that the solution is a character string, but the problem definition requires that it should.

Only works for scalars of course.

David Young submitted a Comment to Problem 341. count to vector

It would be helpful if the text gave an example. Also, the test suite should be much richer - only two special cases does not really encourage people to write general solutions.

... though, just to be clear, the comment wouldn't be quite right, it still needs a little adjustment.

This could be quite a good solution, if you removed the "x = 7; %" part and just left what is now a comment. As it is, although it satisfies the test case, it doesn't actually solve the problem.

David Young submitted a Comment to Problem 116. Distance walked 2D

Needs a richer test suite. A lot of "solvers" have just put a=7 as the "solution", but although this satisfies the single test case, it doesn't solve the problem as stated.

David Young submitted a Comment to Problem 314. Find the sum of the elements in the "second" diagonal

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.

But you can't rely on x always being a magic square - that's just an accident of the inadequate test suite, isn't it? So although this *looks* like a good solution, it isn't really. I think it's bad practice to take advantage of an inadequate test suite.
