Feed Pigeons
When I start to feed my pigeon, a minute later two more fly by. And a minute later another 3. Then 4, and so on. One portion of food lasts a pigeon for a minute. In case there's not enough food for all the birds, the pigeons that came first, eat first. Pigeons are hungry animals and eat without stopping. If I have N portions of wheat, how many pigeons will be fed with at least one portion of wheat?
