3rd Week of CSC 165

This week's my slog topic would be tutorials. The first tutorial that was held last week was straight forward. The pre-tutorial questions were challenging, but as I had a conversation with my peer during tutorial, I became to understand the material completely. First quiz was easier than I thought and I finished it as soon as I got the quiz.
However, second week's tutorial exercises did not go well. They were hard for me and I mostly guessed the answers even though I took enough time to think and try to solve them. I decided to ask the questions during the tutorial session. However, this was where I found an inconvenient thing about the tutorial. There were too many students for one TA, so I waited a long time to ask questions. There was no time to ask TA about the assignment. For the tutorial exercises, I worked, asked and brainstormed with other groups to figure out the answers. I would rather having TA to show the solution on the board in front of the class when there are so many students having difficulties about the same tutorial exercises. Quiz was, fortunately, easier than I thought.
This week's problem solving case I did with Polya's approach is the following:
"Grasp one end of a strip of paper between the thumb and index finger of your right hand, and grasp the other end between the thumb and index finger of your left hand. Fold the strip of paper once, so that the end of the strip that was in your left hand now is on top of the end that was in your right hand, and the thumb and finger of your left hand now grips the fold at what was the middle. If you were to unfold the strip of paper now, it would have a single crease in a direction you might want to call "down". What pattern of "up" and "down" folds do you get?"

1. UNDERSTANDING THE PROBLEM
We are to find the pattern as we keep folding n times. Given information would be how it is considered up or down.
2. DEVISING A PLAN
I would record the pattern of ups and downs as I fold each time and look for a specific pattern.
3. CARRYING OUT THE PLAN
1:                D
2:            U  D D
3:        UUD  D UDD
4:  UUDUUD  D UDDUDD
(U represents up and D represents D)
This is what I found as I folded 4 times. I saw a pattern of UUD and UDD being added at each ends with D being the center as I fold once more. So if I fold 5 times, the pattern would be:
UUDUUDUUD D UDDUDDUDD
4. Looking Back
The question asked for the pattern of "up" and "down" folds I get. I successfully found the pattern.

I have an assignment due next week, so I better ask questions about the assignment as soon as possible. I should visit computer science help center or professor's office hours.
