CS 61B 在职学习Data Structure 打卡

费时2h做完了project 0。一周做完正常学校一周的教学🤦。看来快速解决这门课是不太可能了。希望之后暑假不工作了能刷的快一些。

补充下project0的submission

费时5.5h做完了project 1a。

Week 3 看完了
Java的inheritance真的很清楚。发现之前的lab都没有做。

做完了project 1b，费时1h多一点

Week 4
看完了所有的lecture
- interface
  - one class can implement multiple interfaces
  - all methods are public
  - methods without "default" -> no body, must be overrided
  - methods with "default" -> has body, no need to re-implement
- abstract class
  - one class can extend only one class
  - can have private methods, any type of variables
  - methods without "abstract" -> has body, no need to re-implement
  - methods with "abstract" -> no body, must be overrided

- higher-order function: 必须要以class形式存在

做完了midterm 1。感觉可以直接开始看Princeton的algorithms？

回复错课了 要去CS61A
