Inference and Counting Lines

On week 7, we summarized some rules of inference. I was familiar with them because I had used them for several weeks. After that, our professor introduced some basic sorting strategies and explained how to count lines or steps with his example of linear search.

I did not use the way I learned to count steps on the quiz because the numbers were small and I thought to count directly was more efficient. But I wouldn't do it again anyway because I did not get full mark.
