13.Define the data structures term garbage collection.
14. Describe the garbage collection method for the Unsorted-Optimized array structure.
15. You have coded an application for your friend's business that uses an Unsorted-Optimized array to store the venture's data. One day your friend informs you that the speed of the operations performed on the data set seems to be getting faster and faster. Explain how this could happen.
16. An application's data set will consist of five different types of nodes. Is the data set homogeneous or heterogeneous?
Explanation / Answer
13.Define the data structures term garbage collection.
Answer:
garbage collection (GC) is a form of automatic memory management. The garbage collector, or just collector, attempts to reclaim garbage, or memory occupied by objects that are no longer in use by the program.
The idea of reclaiming the storage associated with a deleted node is called garbage collection and all data structures that support the Delete operation must provide some form of garbage collection
14. Describe the garbage collection method for the Unsorted-Optimized array structure.
Answer:
The garbage collection method for the UnsortedOptimized array structure overwrites the deleted node’s reference using the delete algorithm.
Which, in effect, is calling java’s built in garbage collector to come and free the memory allocated to that node

Answer:
This is most likely because there are in fact nodes that are being accessed at a higher frequency relative to the othernodes; as more of them bubble to the top – the algorithm executes more quickly.
16. An application's data set will consist of five different types of nodes. Is the dataset homogeneous or heterogeneous?
Answer:
Heterogeneous
