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。
It's not true, by the way, of all programming languages. In fact, Professor Guttag already talked about that, in some languages lists take a time linear with the length to get to it.
顺便说一句这在大部分,编程语言中做不到,实际上Guttag教授已经说过这一点了,在一些语言中取得数组,要花费时间是线性长度的。
In Scratch you may have realized that, "I could implement my program this way with these puzzle pieces, but it kind of feels -- like I could use these puzzle pieces instead" -- that's absolutely the case in programming.
在Scratch中你可能已经意识到,“我可以用这一段代码来,执行我的程序,不过这有点感觉到,我可以用这些代码段来代替“,那绝对是编程中的一个情况。
