All you need to do is take the "power" value less than or equal to the greatest number. Ie, 512 because the next "power" number is 1024 which is too great. So, 2,4,8,16,32,64,128,256,stop Max -----Original Message----- From: accessd-bounces at databaseadvisors.com [mailto:accessd-bounces at databaseadvisors.com] On Behalf Of Shamil Salakhetdinov Sent: Sunday, April 25, 2010 7:52 PM To: 'Access Developers discussion and problem solving' Subject: Re: [AccessD] OT: Friday Puzzles BTW, the answer for the fist puzzle is as straightforward as this code (C#): public static int GetSurvivorNumber(int lineSize) { return (int)Math.Pow(2, (int)Math.Log(lineSize / 2, 2) + 1); } Got it last night "out of nowhere"... Of course Drew's original "brute force" solution was a 'must have' step to get to the above 'lightweight' answer... Or one have to get studied in the modern computer science colleges where they are taught to "crack" such puzzles in seconds...

It's very interesting how many of you readers are so easily diverted from what might have been productive work! I shall endeavour to come up with more puzzles for you all. It's also interesting that you all focused on the survivor problem. Everyone seems to have ignored the other one.
