Week 1提到的different style指的是會提供一部分代碼,然后根據這部分代碼進行擴展(但不能修改這部分代碼)。并且請使用和自動評分相同的Ruby版本。
Week 2學習的視頻比較少,但是有一個更具挑戰性的作業(會同時用到Ruby和ML)。The idea behind the assignment is to take some ML code and port it both to Ruby and to an object oriented style.
Week 3,比較和對比子類型、子類型的泛型。It'll actually focus on concepts for both part B and part C。
