7th Week of CSC 165

All the first term tests are done and I am trying to adjust to normal life again. Since midterms put me into position where I could only study the upcoming test, I have lost in track of CSC 165 materials. I went to the tutorial without any knowledge of proof. However, my classmates and the TA helped me, so I did the quiz well. I decided to look up the course slides from week 4. The due date for the assignment 2 is coming, so I have to do it. This week's problem solving question was penny piles.
