It's a long sequence of instructions, it starts at the beginning, walks through, may jump around a little bit, but eventually comes down at the end. It's okay for the things you're doing for the early problem sets.
这是一长串指令,从开端开始,向前步行,偶尔来回跳一会儿,但是最终会走到结尾,这些足以解决最初级的问题。
Well, realize one of the themes in this course and really one of the themes in programming and solving any problem with a machine is going to be really to just take small bites one at a time out of these problems until the end result ultimately is that you've actually bitten off a fairly large fairly interesting problem and in the aggregate, you've actually implemented something pretty sophisticated.
好吧,让我们先想一下这件事带给我们的主题,编程和解决问题的思想,一台机器最开始只会一步一个脚印,沿着要解决的问题向前迈进,直到最终的结果出来,最后你会发现,你已经解决了一个相当大,相当有趣的问题,而这个问题在最初看起来确是相当复杂的。
Is the first part. That says, I took the branch through here that eventually got to the end and said, there wasn't a solution, in which case I'mgoing to print out, there ain't no solution, otherwise I'll print out the pieces. All right, let's check it out. Ah, what did I say?
我是否返回了特殊的none值?是第一部分,这里的意思是我从这个分支,走到这儿最终走到最后,并告诉我这条路没有解决方案,也就是我想要打印的结果,没有符合的结果,否则我会把它们输出来?
