 the cyclist submitted a Comment to Solution 703651 No, the trick is actually fairly poor coding practice on 18 Oct 2016 the cyclist submitted a Comment to Solution 994062 https://www.mathworks.com/matlabcentral/fileexchange/34754-calculate-size on 5 Oct 2016 on 5 Sep 2016 the cyclist submitted a Comment to Solution 923890 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. on 16 Jul 2016 the cyclist submitted a Comment to Solution 903585 Changed test suite to deny this "solution" on 14 Jun 2016 the cyclist submitted a Comment to Solution 66738 Changed test suite to deny this "solution" on 14 Jun 2016 the cyclist submitted a Comment to Solution 14129 Changed test suite to deny this "solution" on 14 Jun 2016 on 20 Aug 2015 the cyclist received Leader badge for Solution 717906 on 20 Aug 2015 on 20 Aug 2015 the cyclist submitted a Comment to Solution 703651 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. on 21 Jul 2015 the cyclist submitted a Comment to Solution 563857 Although MATLAB does create a 2x2 matrix as an output from magic(2), that output is not a magic square. on 27 Jan 2015 the cyclist submitted a Comment to Problem 149. Is my wife right? Sneha, do you really want to tell your wife to get 'out'? on 31 Oct 2014 the cyclist submitted a Comment to Solution 489566 Glad you claimed the lead! on 22 Aug 2014 on 22 Aug 2014 on 22 Aug 2014 on 4 Aug 2014 the cyclist submitted a Comment to Solution 480291 I added another test to the suite that invalidated this cheesy solution. on 30 Jul 2014 the cyclist received Speed Demon badge for Solution 10200 on 30 Jul 2014 the cyclist received Speed Demon badge for Solution 10200 on 30 Jul 2014 the cyclist submitted a Comment to Solution 406838 New test suite invalidates this solution. on 20 Feb 2014 on 20 Feb 2014 on 20 Feb 2014 the cyclist submitted a Comment to Problem 2202. Flip the bit Added this check. (I messed it up a bit the first time I tried to do it, so sorry for some interim weirdness.) on 20 Feb 2014 on 20 Feb 2014 Good suggestion. I've added a couple more tests to the suite, including one that has three columns in the logical mask. on 13 Feb 2014 the cyclist submitted a Comment to Solution 363762 http://www.mathworks.com/help/matlab/ref/assert.html on 4 Dec 2013 on 26 Nov 2013 on 26 Nov 2013 the cyclist submitted a Comment to Problem 160. So many choices @Sumit, you are probably using a function from a toolbox (e.g. statistics toolbox) that is not available to Cody. on 11 Sep 2013 on 22 Aug 2013 on 27 Jul 2013 on 30 Jun 2013 on 30 Jun 2013 on 30 Jun 2013 on 30 Jun 2013 on 7 Jun 2013 the cyclist submitted a Comment to Solution 203610 I added a test case to nullify this "solution". on 25 May 2013 the cyclist submitted a Comment to Solution 214423 This solution only tests for divisibility by 9, not whether the number is a Kaprekar number. on 9 Mar 2013 the cyclist submitted a Comment to Solution 27245 Added to test suite to eliminate this "solution". on 9 Mar 2013 on 8 Mar 2013 on 8 Mar 2013 on 8 Mar 2013 on 8 Mar 2013 the cyclist submitted a Comment to Problem 151. Magic! 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.) on 8 Mar 2013 the cyclist submitted a Comment to Problem 151. Magic! 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. on 8 Mar 2013 the cyclist submitted a Comment to Problem 162. High school cafeteria 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. on 27 Feb 2013 on 13 Jan 2013 on 13 Jan 2013 on 13 Jan 2013
