A farmer is trying to cross a river. He is taking with him a rabbit, carrots and a fox, and he has a small raft. He can only bring 1 item a time across the river becuase his raft can only fit either the rabbit, the carrots or the fox. How does he cross the river.
(You can assume that the fox does not eat the rabbit if the man is present, you can also assume that the fox and the rabbit are not trying to escape and run away)
What is
Step 1) Take the rabbit to the other side.
Step 2) Go back and get the Fox and switch it with the Rabbit
**The key here is that the carrots and the rabbit are not being left alone.
Step 3) Take the carrots across.
Step 4) Go back and get the rabbit.
