Week 4

In week 4, We have learned Recursion, this is kind of a hard topic. I really enjoy the binary code example, which is make easier to understand how the recursion works, but I'm still hardly to create my own recursion function, my mind always thinking into the "while loop" part. Next week's lab will probably doing the recursion, I hope I can get better understanding in this thing. This week lab we did the car travel staff, in the beginning I got confuse at the (x,y) location part, but after that it was a pretty fun lab
