CS #3: Data Structures
    Data structure is how we organize or store data. Some are more efficient than others.
    
        - Most companies will ask you about data structures during the interviews, so pay attention 
- Types of data structures:
            - ArraysFixed size. Allocated memory is always the size of the array, even if not being used.
- Linked ListData is linked using pointers. Dynamic size. Easy to add or delete.
- QueueFIFO. Enqueue (add) and Dequeue (remove first).
- StackLIFO. Push (add) and Pop (remove last).

- Objects - more complex data types
            - List<Student>
