Lesson 2. Game together across the bridge. Four people need to cross a bridge. Because of the weak demand, each time we go not more than two people, and because it is dark, we have to take the light.

Since there is only one lamp, each passage must be carried back to the next person. When two people go together, cross the bridge with a slower time. The following example is a way to go: - 10 minutes to go with people 5 minutes to bridge, 10 minutes to take. - 5 minutes to take the lamp back, take 5 minutes. - 5 minutes to go with people 2 minutes through the bridge, It takes 5 minutes. - 2 minutes to take the lamp back, take 2 minutes. - 2 minutes with people 1 minute over the bridge, take 2 minutes. Total time is 10 + 5 + 5 + 2 + 2 = 24 minutes. Let's try to get away with a little less time as possible, and if less than 19 minutes is great
