Lab3 and Lab 4
 

I finished both of them and submitted. The professor provided a sample Alice while using the array. I did quite well; however, somehow I could not drop multiple rings at the same time randomly. Another challenge was I could not catch any ring. Even I am very closed to the ring or I almost catch one, the cathing point did not increase in the Lab4 assignment. I like trying and failing method so I try various ways to accomplish my ultimate goal.
