All Journeyman and Scholar members, including YOU, have that 'inside' advantage.  Few, however, have programming ability comparable to Charlie's.  There is certainly nothing wrong with using a program on this problem -- the problem did not prohibit such.  There can still be a comment that provides analysis explaining the solution that Charlie found, and the question of uniqueness could bear some analysis as well, I would think.  The problem has a difficulty rating of 2, so if that is accurate and based on no program being used, somebody should be coming up with those analyses very soon. If not,  that will indicate that the problem wasn't interesting enough to pursue without a program, and not that Charlie spoiled it, in my opinion.
