Puzzle

For those who've missed it, here's an exellent maths [url=http://www.dominating12.com/forum/?cmd=topic&id=1251]puzzle[/url]. Except that maths as I know it is not so much about numbers and formulas, as about logical thinking. So goodluck :) Once upon a time in Soviet Russia comrad A. [b]A[/b]damns added a rooster to his fine collection of chickens. Now the frequently loud noises early in the morning greatly annoyed his two neighbours, comrad B. [b]B[/b]rown and comrad C. [b]C[/b]hrzanowski. Instead of making a fuss about it, they decided to talk it out. At the end of the day they did not find a good solution. Instead, they decided they hated each other so much they would never speak with eachother again. This resulted in a small problem. You see, everything they need they can buy at one of the three special ussr-you-can-buy-everything-mega-stores, except for [b]D[/b]oughnut's, [b]E[/b]ggs and French [b]F[/b]ries. These can of course be bought at the designated speciality stores, designed to show the outside world that small businesses can also thrive in the soviet union. Unfortunately there is only one shop for [b]D[/b]oughnuts, one for [b]E[/b]ggs and one for French [b]F[/b]ries. Can the three neighbours find paths so that they can get everything they need at any time they want, without the risk of bumping into one of their neighbour comrades (which means having to greet them)?

Hmm, I'm not sure I completely understand the problem. [spoiler]If the neighbors need to be able to go to any store at any time they want, they can't be sure that another will come at the same time. Am I missing a piece of information or not reading it right? Or do I just have to approach the problem differently?[/spoiler]

You are right, it is actually true that if they time it right they will meet each other in the shop again, but lets assume that in there they don't have to greet eachother when inside one of the three stores.

The guy with the chickens doesn't need to visit the egg store

"Can the three neighbours find paths so that they can get everything they need at any time they want, without the risk of bumping into one of their neighbour comrades (which means having to greet them)?" The answer to your question in it's entirety would be a resounding; Yes
