Sorites Solution - another suggested problem

Dear Vladimir, Hi, and sorry for delay!

The problem is ready! I guess some people may be tempted to try solving it with pencil and paper (or completely "in the head" as a memory exercise) - since just reading these random statements may provide much fun :)

Very nice, thanks.

PS The wikipedia link needs correcting.

Yeah, thanks Friends, sorry for my inattentiveness - now fixed :)

BTW your puzzle reminded me of some other - have you ever seen the old DOS game Sherlock? Its goal is to select one of six houses, one of six persons, one of six fruits etc using logically a set of clues...

Hi experts,

Sam,

Sorites is a sequence or chain of logical implications. You are asked to build one that uses all 30 statements. Print out the chain for your solution and check its length - you will find that yours only uses 5 statements. One more hint: play water polo is only appearing once in the 30 statements. That means it has to come either at the start or the end of the chain.

Thanks guys, I found the bug. All good now. Task done. Thanks again.

Cheers, Sam.

Hi Gardengnome, Mate, what is the logic behind your program, my program has 60+ lines, but wrote it in less than 20 lines. Impressive.

Hi Zelvin, That's a beautiful piece of code mate. Appreciate it if you can explain the logic behind the code. It will definitely help a beginner like me.

Cheers, Sam.

Thanks guys! I will follow the thread

         Thanks both!!!
