Three jackals and three coyotes are on a trek across the Mokalani Plateau when they come to a river filled with carnivorous fish. There is a rowboat in sight, and the party decides to use it. (Both species are known for their cleverness.) However, the boat is too small for any more than two of the group at a time. So they must traverse the river in successive crossings. There is on hitch, though: The jackals must not outnumber the coyotes at any time, in any place. For example, if two jackals and only one coyote are left alone on the western side of the river, this problem is reduced to simple subtraction: the jackals will overpower, kill, and eat the coyotes. It’s okay to have an equal number of each, and it’s also okay to have more coyotes than jackals in a given place –neither situation poses a danger to the coyotes, and the coyotes do not pose a threat to jackals. So, the trick here is to use the one small rowboat, a lot of sweat, and a little brainpower to ensure the coyotes’ safety while both groups cross the river.

*To get across the river, the boat needs an animal to be in it.

Two jackals on the boat, leave one on the other side, go back, get a coyote, drop it off, go back, get another coyote, drop it off, go back, get the last coyote, drop it off, go back, get the jackal, drop it off and the jackal driving the boat gets off too. Keep in mind there is one jackal at the boat at all times. (i may have misunderstood your question)
