Week1 Introdcution and Simple Induction

The first class of CSC236 was taken on the fourth day that I start to study in UofT (I'm a newly admitted transfer student). Frankly speaking, I was a bit nervous to attend the first class, afraid of missing some basic background information because I didn't take the CSC165 courses.

However, fortunately, the first class came as a relief to me. The materials covered in the first class were mainly focused on Simple Induction (we mainly called it Mathematical Induction in high school), which is not hard.
The following is my lecture notes taken to prove some problems:
