Alfonso Nieto-Castanon submitted a Comment to Problem 1187. Knave in the middle attack

thanks for the heads up and temporal fix. I am still looking into this, it seems that the issue was probably a change in memory-management affecting function handles in some of the more recent Matlab releases, and I should probably just change the way I implement the Knight/Knave answer function to explicitly allow self-references...

Alfonso Nieto-Castanon submitted a Comment to Problem 2825. pay it forward

@Rafael: thanks for you comment, and I guess you are right and kindness is in the eye of the beholder, but for example I see your solution using y=10 relying on Jonathan's kindness (as he submitted that 10 before you did), and similarly I see your failed -but kind!- y=50382 solution hopefully helping some other player solve this problem in the future, effectively paying that kindness forward (thanks!). That said, perhaps Jonathan, or you, were not really trying to be kind to others with their failed solution attempts and were instead just trying out some random solutions, but hey, I like my interpretation better :)

it's a bit unclear why padding is necessary in the first two test cases, where the number of characters (15) is already a multiple of the key size (3 or 5, respectively)
