Seriously? We just started. You know, read the text book, making sure to understand. I'm in Chapter 3 at the moment, so still not ready to answer the first question of the assignment.
Well I read through chapter 3, wasn't still able to answer Q1, or at least I'm not satisfied with my attempt at it, so I went on to the next question, which I understood a little better. I'm excited about the last question. Its soo much fun.
I see what you mean about the last question. It appears that it still relates to Chapter 3. But, at least they not asking for a search algorithm, yet. Perhaps drawing a diagram to illustrate the search problem may provide a better understanding of the puzzle.
