Today, we continued on the left problems for chp9 exercises. I was working on 9-c but.. I was not sure whether that is a problem to solve or to just look and understand, so I just skipped and went on to exercise 7. Luckily, as soon as I decided to do that, Mr.W asked everyone to go over no.7. Then, he talked about three ways to do traversal.
