sson 1. Lan in the apartment number? Lan house is in an 8 storey house, each floor has 8 apartments. One day, the class asked Lan: "What is your house in the apartment?" "Ask me some questions, I will answer all your questions, but just say" yes "or" no. "Through these questions you try to figure out how many in the apartment" Huy said: "I will ask, are you in the apartment number 1, number 2, ..., No. 63. So with most 63 questions you will know which apartment you. You say, "I only need 14 questions, 7 sentences enough to know what floor you are on and 7 you can know exactly what you are in the apartment." Dear children, I have to ask several times to know.

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. Four people walk differently, crossing the bridge with corresponding time of 10 minutes, 5 minutes, 2 minutes and 1 minute. 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
