By paul2Binary Trees. Linear data structures. Here are some of the data structures we have studied so far: Arrays Singly-linked lists and doubly-linked lists Stacks, queues, and deques Sets These all have the property that their elements can be adequately displayed in a straight line
By AudreyB-Trees. Motivation for B-Trees. So far we have assumed that we can store an entire data structure in main memory What if we have so much data that it won’t fit? We will have to use disk storage but when this happens our time complexity fails
