csc148 week 7

This week we have learned more about the recursion like last week. However, this week, we have learned more deeply about it and we have talked about the tree abstract type. In those 2 weeks of learning, I became more and more familiar with recursion and how to use it. It's a very flexible use end very efficient. This also furfill my interest to computer science. Then I am looking forward that we can learn about when to use recursion in the future week. This week is such a great week !
