week 11 revisit earlier slogs

1) revisited the slog 'why geeks should write?'.  I am completely agree what I thought. Writing before programming is so important and it helps to organize and structure thoughts.  And when the code is finished, it is easier to track through it.

·      “I think it is important for programmers to "write" because it allows us to keep track of our progress. Keeping a SLOG allows us to set goals, take note of ideas we have not fully grasped yet for revisiting, and track backwards to see how we developed certain perspectives.”

Ideas in the slog above are quiet similar with me, and those slogs helped me lot. Reading other slogs helps me to understand the course concepts, Some ideas in the course are hard to accept if I never experienced before, but through slogs, I can understand them easily because some concepts which are explained by students is easy to read.

2) For recursion in tree structure, I am quiet confident with myself through lots of practices.
