Algorithm problems-ideas and knowledge-how to obtain the Boeing 747 weight

Interview Questions for a company:

How to get the Boeing 747 weight is an open question. How can you answer this question.

In fact, this issue is not specific.AlgorithmThe problem is your idea of solving the problem. Can you solve the problem if you have insufficient knowledge?

This capability is very important to developers. However, different levels of knowledge may have different ideas. The answer here is not a standard and is only for reference.

1. If you have no knowledge at all, you can refer to the answer

A calls Boeing and asks about the weight.

B. Buy a ticket, ask the captain on the plane, or ask the maintenance personnel at the airport.

C. online query (Active answers are supported)

2. Have some knowledge and can make an analogy

For example, the United States's largest C-5 can transport 2 M1 tanks, M1 weight is 60 tons, so the load should be, 120 tons, according to a ton of load and aircraft weight is about-4 Calculation

C-5 is about 360-480,

Assuming that the C-5 is 20% larger, Boeing's weight is between 350-tons, and the center is about

This problem mainly depends on whether you have enough knowledge. If you have a little knowledge, you must make bold assumptions and analogy to estimate a value with a relatively large error,

This does not matter. The key is that you know how to solve the problem and then gradually improve. This is a major idea of formal project management.
