Linked Lists

When I applied to graduate school in Computer Science, I was told to learn data structures and give them a call back. Ouch. I did eventually pick up a whole class on data structures. It was actually quite fun. This knowledge can help you through a question during an interview which centers around common data structures.

The most basic and favorite data structures for interviewers is the linked list. Obviously there are different types of linked lists. But for all of them you should check for NULLS when traversing it. You also need to know that deleting a record in the list requires at least two pointers.

Oh snap. We are out of time. Next time I will talk about the types of tree data structures in computer science.
