Eleventh Entry
"Out of the island, ahhhh!"
So, today was hectic. It took forever for my friends and me to finish project #2. I wouldn't have been able to finish this cumbersome project without the harmonious corporation we achieved. I even sent a devastated e-mail to my TA, which was done only out of my 'freaking out phase', but we ended up finishing it well.
As for preparing for the final, I am planning on re-reading all the lecture slies and my lecture notes. Watching the Racket videos will help refresh my mind about the definions and codes we have been learning throughout the year.
Thank you Professor Heap! I mean, to be honest, not many people show up in the morning and it could strike a professor as annoying or discouraging, but you still hold engaging lectures for those who do keep the interest in the subject and make this course a pleasant experience for us. I appreciate your effort to implement every detail of this course. My last slog entry, and my time to depart the island. :)

Because Ji Soo Kim and I did the problem solving together, I am going to post the photos of the sheets we worked on and briefly explain what is going on there. She is going to post link to my slog. We worked on Penny Piles.
First, can you arrange things so that one of the drawers has 48 pennies, using combinations of the following two operations, which we put in equation as L has even => L/2 => R and R has even => R/2 => L. The answer is yes, and it works if you work backward.
Second, choose another number in the range [0, 64]. Starting from the same initial position, can you arrange things so that one of the drawers has the number of opennies? Yes, and we did it by drawing the tree of numbers. Are there any numbers in that range that are impossible to achieve? I don't think so.
Third, what about starting with a different number of pennies in the left drawer? I mean, for sure odd numbers are impossible. And also numbers that are outcomes of 2 to the power of k, and k being 0, 1, 2, 3, 4, 5, or 6 will work, but not all multiples of 2 will work.
