Ned Gulley submitted a Comment to Problem 44363. Is this is a Tic Tac Toe X Win?

@Sean, I think Doug's got it right. He's asking only if the X side (that is +1) is in a winning position. In test 7, the O side (-1) is in a winning position. So the answer given is correct.

You need to assign your answer to the output variable tf.

Look at your result carefully when n = 4.

Ned Gulley submitted a Comment to Problem 1686. Generate a melodic contour string matrix

I admit they look wrong, but the actual text in the MATLAB code runs properly. I just re-scored some answers and they worked fine. It must be some kind of HTML display problem. I'll check into it.

Hi Peter: If your problem is still incomplete, just leave it in draft mode. Don't publish it until it's complete.

Good point. Fixed this.

Ned Gulley submitted a Comment to Problem 581. Function composition

I guess the name needed changing, but be aware that if we ever re-score old entries, everyone who passed before the name change will now fail, since they will now be calling the wrong function.

Good suggestion. I made the change.

Ned Gulley submitted a Comment to Problem 43886. Degrees to Radian

Hi Jared. If you're going to make problems that have approximate floating point answers (often the case with conversions), you need to allow for some variation in your test suite. ISEQUAL is not a good test in these cases. Instead, maybe use ABS(answer-correct) < tolerance.

Ned Gulley submitted a Comment to Problem 43830. MPS to MPH

Hi Jared. Please specify what MPS means. I assumed it meant meters/second. I had to inspect your test suite to figure out you meant miles/second. Also, your problem title says MPH to MPS, but the actual problem is to convert MPS to MPH.
