Two merchants have 5 camels each. One fine day, one of the merchants sells all of his goods in the market and heads back to the village. He has to cross a bridge to reach his destination, and the bridge is only wide enough for 1 camel at a time.
At the same time, the other merchant is heading to the market to sell his goods and must cross the same bridge. Alas! They meet up in the middle of the bridge one camel-length from each other. They are both stubborn and won't back up their camels. Fortunately, the first merchant's camels are spry and unladen and are able to jump over another camel. Can both merchants get their camels across the bridge? (Both merchants' camels can jump)
