2 men and 2 boys want to cross a river. None of them can swim and they have only 1 canoe. They can all paddle but the canoe will only hold 1 man or 2 boys.

How do they all get across? What is the minimum number of crossings required?

Both boys canoe across the first time, and one boy brings it back.

A man canoes across on the second trip, and the boy brings it back.

The two boys again cross the river, and one brings it back.

The other man makes the fourth crossing, and a boy brings it back.

The fifth crossing is made by both boys.
