mit 计算机科学及编程导论（4）

拖了一周才又写总结，看来所有东西要坚持都是不容易的。

word:

decompose , module , isolate , suppress , bury , analogy , documentary , drama , chunk , specification , contract , replicate , case-sensitive , funky , implicit , shutter , constrain , flame , gear , equation , inversion , brute-force , wrap , encapsulation
, silk , algebra , palindrome , geometry , rap , knuckle , converge

notes:

1、decomposition : isolate modules

2、abstraction : suppress details

3、functions : one of the mechanisms to capture decomposition and abstraction

4、how to write functions : specify the inputs and outputs and leave the details to programmer

5、how to use functions to think about problems : recursion ( 1、base case ; 2、inductive step : break program into small version of the same problem and some other steps )

6、figure out what problems are suitable to be tackled by looping and what to be tackled by recursion

ps：

老外学东西讲究来龙去脉，要知道为什么用，例如使用函数就是为了模块化和抽象化；但是中国人学这个就是使用，老师教的时候也不说为什么，就说要把代码分割成函数，也许他们也就是这样过来的。
