Third SLOG

    During this week, I faced some difficulties when I tried to trace back recursive function. I could trace simple recursive functions but when functions are complicated, I found that I always made mistakes. Not only complicated functions are difficult for me, but also those tricky functions. I often made tiny mistakes when I traced back because I am a careless person so I think I have to do a lot of practice to do well in this section. However, recursion is so useful that I can use two to three lines to do something that I have to write many lines to do so. With recursion, a lot of things are getting easier although I sometimes make mistakes. 

Impression of first few weeks

    For the first few weeks, I found out that the material learned in csc148 was very different from csc108. Although these two courses focused on the same computer language, csc108 was like an elementary course but csc148 was more like a high-school course. The most impressive thing for me was Abstract Data Types. I thought we could only use the built-in methods in Python last semester, but now I know that I can create my own class and do whatever I like. For example, we learned Stacks in class. This method seems useless at first but I found that it’s very useful when I want to just add things on the top or “pop” something out from the top. Before I learned that, I may have to use while loop or for loop to do so. However, with Stacks, I can just write one line to do so.
