The sheet basically was showing us the under workings of a function called "lolcatz" and how we were supposed to help finish an incomplete version of the "lolcatz" function.
I was sitting beside a friend and we were constantly looking at each other with looks of despair, followed by my friend asking the TA multiple questions about the sheet till the end of class. When class ended my friend and I walked out of class with looks of despair about what just happened in the lecture.
Lets jump to Thursday night where I was cramming for the quiz on Friday when I realized the video tutorials I was watching generally explained what happened in Tuesday lecture. As of now looking back at the Tuesday lecture sheet, I finally understand a bit of what is happening on that sheet!
