And ask yourself, what problem have you solved, ever, that was worth solving where you knew all of the given information in advance; where you didn't have a surplus of information and you had to filter it out, or you didn't have sufficient information and had to go find some.
问问自己，什么问题你们解决过的， 值得解决的， 在此问题中，你提前知道所有信息， 或者你没有多余信息，然后你需要过滤信息， 或是你没有足够的信息， 你需要去查找些信息。
