I've been a tutor for this past semester to students taking Introduction to Programming. Many who have come to my session are moving on to Data Structures next semester. They asked if they could have a primer as to what to expect. I have some resources that I have found helpful both while taking the course and tutoring it in the past. It will take me a little bit to compile a good list of those, but for now, here is a bare-bones list of topics of topics you might expect to see for a data structures course: Part 1: - Running time of code segments (Big-O Notation) - Abstract Data Type (ADT) - Interfaces (when to use "implements", cannot instantiate them, what inheritance is) - Superclass, subclass, method overriding/overloading - Abstract classes Part 2: - Binary Search Trees - Stacks (and its four methods — push, pop, peek, empty) - Linked list (single, double, circular) - Prefix and postfix notation (compare to infix) Part 3: - Min/Max Heap - Hash Table
