I think it's about time for you to get reeeeeaaalllllyyyyyy bored at work.


I am quite bored. I'm a little bit ahead of schedule, so I gotta kill some time.

OK let me add two things:

The philosofers are "blind".

The philosophers already grab one fork at a time. Imagine all of them grab the left one at the same time, and they all go with their hands to the right one, and of course they won't find the right fork. They'll just wait in that position, and this will lock things up. Now, define a rule for the philosophers to follow, so a lock up never happens.

It's almost that. Just think a little bit harder and you'll get it.

And no, no coding please. This is "riddles", not "coding".

Now, between each plate there is only one fork, so that a filosofer can see his plate, a fork on the left side, and a fork on the right side. OK? Now, every filosofer will start eating his spaghetti at a random time, eat it for a random time, and stop eating it at a random time, the proceed to eat again, ad infinitum. When a filosofer decides to eat the spaghetti, he'll reach for BOTH forks and proceed to eat. The problem is, if a filosofer grabs a fork, let's say, on his left side, the filosofer to his left can't grab his RIGHT fork, get it? Now, if a filosofer wants to eat, and he can't get both of his right and left forks, he'll just stay there, waiting for the fork. Unfortunally, this can lead to a lock up if every filosofer grabs one fork. Now, you gotta decide a special rule so that this scenario never happens, and the filosofers never lock up.


Since I got the last one right, this is my riddle. It's not as insane as it may seem, it's actually as easy as the ball one.

It dosen't, because it's like throwing a dice twice and getting sequential numbers.

It's a good probability problem, the "same birthday" one... It's one of those "I can't belive this is the answer" problems.
