I you take a look at the lower 6, you'll see it has no neighbor with a lower altitude (pay attention to the rule quoted above, it says only LOWER not LOWER OR EQUAL), only one with the same altitude (the upper six), and 2 neighbors with a higher altitude. So the lower 6 is also a sink, that's why you have 2 flows. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "google-codejam" group.
