Data Structures & Algorithms I: ArrayLists, LinkedLists, Stacks and Queues (edX)
Work with the principles of data storage in Arrays, ArrayLists & LinkedList nodes. Understand their operations and performance with visualizations. Implement low-level linear, linked data structures with recursive methods, and explore their edge cases. Extend these structures to the Abstract Data Types, Stacks, Queues and Deques.

The Data Structures & Algorithms course begins with a review of some important Java techniques and nuances in programming. The course requires some prior knowledge of Java and object-oriented programming, but not in data structures or algorithms. This course introduces you to time complexity, and threads this concept throughout all data structures and algorithms presented in the course. You will work with the principles of data storage in Arrays and LinkedList nodes. You will program the low-level data structures: Singly, Circular and Doubly LinkedLists; and explore edge cases and efficiencies. LinkedLists and Arrays are used to implement Abstract Data Types, ADTs: Stacks, Queues and Deques. Harnessing the power of recursion to move through these data structures is necessary. As the size changes in your data structures, it becomes important to examine amortized analysis of the operations.

The course design has several components and is built around modules. A module consists of a series of short (3-5 minute) instructional videos. In between the videos, there are textual frames with additional content information for clarification, as well as video errata dropdown boxes. All modules include an Exploratory Lab that incorporates a Visualization Tool specifically designed for this course. The lab includes discovery questions that lead you towards delving deeper into the efficiency of the data structures and examining the edge cases. This is followed by a set of comprehension questions on topics covered in the module that count for 10% of your grade. The modules end with Java coding assignments which are 60% of your grade. Lastly, you'll complete a course exam, which counts for the remaining 30% of your grade.

This course is part of the Data Structures and Algorithms Professional .

Syllabus


Module 0: Introduction and Review

- Review of important Java principles involved in object-oriented design

- The Iterator & Iterable design patterns, and the Comparable & Comparator interfaces

- Basic “Big-Oh” notation and asymptotic analysis


Module 1: Arrays, ArrayLists and Recursion

- The array class, access vs. search of an array, static allocation and efficiency

- The List abstract data type (ADT) which is backed by an array and uses dynamic resizing and amortized analysis

- Recursive methods that are applied to the array and ArrayList data structures


Module 2: LinkedLists

- The Singly LinkedList data structure, its implementation, methods and time complexity

- The use of the iterable interface and recursive methods in LinkedLists

- Creating variations of LinkedLists such as Doubly-Linked and Circularly-Linked


Module 3: Stacks, Queues, and Deques

- The Stack ADT based on the last-in, first-out principle, and its implementations using Arrays and LinkedLists

- The Queue ADT based on the first-in, first-out principle, and its implementations using Arrays and LinkedLists

- Creating variations of Stacks and Queues such as Priority Queues and Deques
