week 8

I used to confuse the idea of linked lists, with them being one item like a list. Now I realize they are individual items that can be connected, but in a way are still individual. It was useful for them to be explained as either a value with a list connected to it (as if there are only two "items" or as individual objects referring and connected to other objects. I don't understand the point of a wrapper function or more specifically how you use it? I find linked lists interesting and I will keep reviewing the slides, codes and and practice exercises I find, to grasp a better understanding of them. I felt that part a of assignment 2 went well and actually bettered my understanding of tree's, their class and traversal. I was worried before that I wouldn't get a good opportunity to really understand them, but the assignment helped break them down. Even though the assignment was troubling in understanding what it wanted in the beginning or even grasping what regex was. After spending some time with the handout for this assignment, I felt I got the picture.
