Data structures and algorithms are essential in computer science since they play a crucial role in efficient information retrieval and processing, dealing with files, storing contacts on phones, social networks and web searches.

In this course, you’ll learn about the array-based implementation of various linear data structures, stack, and queues. You’ll also learn about linked list-based implementation. Next, you’ll explore advanced data structures like skiplists and hashing. You’ll learn how to implement a variety of trees and graphs, and data structures related to bits of an integer. Toward the end of the course, you’ll learn the implementation of structures based on external storage.

After completing this course, you’ll be able to create reusable programs with template-based collections that can efficiently analyze how to optimize the storage and retrieval of very large amounts of data. Overall, this course will enhance your productivity and performance as a software developer.

Data Structures with Generic Types in Java

Hash tables and hash codes represent an enormous and active field of research that is just touched upon in this chapter. The online Bibliography
on #key# Hashing: Bibliography on hashing. URL: http://liinwww.ira.uka.de/ bibliography/Theory/hash.html [cited 2011-07-20]. #key# contains nearly 2000 entries.

A variety of different hash table implementations exist. The one we discussed before in this chapter is known as **hashing with chaining** (each array entry
contains a chain (`List`) of elements). Hashing with chaining dates back to
an internal IBM memorandum authored by H. P. Luhn and dated January
1953. This memorandum also seems to be one of the earliest references
to linked lists.
