 David Young received Speed Demon badge for Solution 50615 on 26 May 2016 David Young submitted a Comment to Solution 406838 Invalid solution, really on 20 Feb 2014 on 20 Feb 2014 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. on 20 Feb 2014 on 20 Feb 2014 on 20 Feb 2014 on 20 Aug 2012 David Young submitted a Comment to Solution 106284 Only works for scalars of course. on 4 Jul 2012 on 4 Jul 2012 on 16 Mar 2012 on 14 Mar 2012 on 14 Mar 2012 on 13 Mar 2012 on 12 Mar 2012 on 10 Mar 2012 on 10 Mar 2012 on 10 Mar 2012 on 9 Mar 2012 on 9 Mar 2012 on 9 Mar 2012 on 9 Mar 2012 on 9 Mar 2012 on 8 Mar 2012 on 8 Mar 2012 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. on 8 Mar 2012 on 8 Mar 2012 on 8 Mar 2012 on 8 Mar 2012 on 7 Mar 2012 David Young submitted a Comment to Solution 21730 ... though, just to be clear, the comment wouldn't be quite right, it still needs a little adjustment. on 6 Mar 2012 David Young submitted a Comment to Solution 21730 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. on 6 Mar 2012 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. on 6 Mar 2012 on 6 Mar 2012 on 6 Mar 2012 on 5 Mar 2012 on 5 Mar 2012 on 5 Mar 2012 on 2 Mar 2012 on 2 Mar 2012 on 1 Mar 2012 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. on 1 Mar 2012 David Young submitted a Comment to Solution 43073 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. on 1 Mar 2012 on 1 Mar 2012 on 1 Mar 2012 on 1 Mar 2012 on 1 Mar 2012 David Young submitted Solution 54373 to Problem 237. Half? on 29 Feb 2012 on 29 Feb 2012 on 29 Feb 2012 on 29 Feb 2012
