Data Structures and Algorithms
Ace technical coding interviews
Enrollment Closing In
Study 10 hrs/week and complete in 3 mo.
This program will help you gain an in-depth understanding of data structures and algorithms through 100+ practice problems and dedicated mentor support. Learn by doing as you practice with both defined and open-ended questions. This practice will help you learn to design elegant solutions to new and open-ended problems.
“I will, in fact, claim that the difference between a bad programmer and a good one is whether he considers his code or his data structures more important. Bad programmers worry about the code. Good programmers worry about data structures and their relationships.”— Linus Torvalds, Linux and Git creator
Complete over 100 data structures and algorithms problems and four projects to help prepare you for job interviews and on-the-job scenarios.
Learn how to approach well-defined or open-ended data structures and algorithms interview problems and how to implement the appropriate solution based on your design choices.
Advance quickly and successfully through the curriculum with the support of qualified reviewers whose detailed feedback will ensure you learn skills the right way.
Draw inspiration and knowledge from your student community. Stay on-track with the support of the mentor network directly in the classroom when you need guidance on specific challenges or projects.
Python & Basic Algebra.See detailed requirements.
Get an overview of your program. Meet your instructors, and refresh your Python skills. Learn the framework to deconstruct any open-ended problem and then understand the concepts of time and space complexity.Unscramble computer science problems
Learn different data structures that can be used to store data. Implement different methods used to manipulate these data structures and examine the efficiency. Understand the advantages and applications of different data structures. Learn how to approach open ended problems (either in interview or real-world) and select appropriate data structures based on requirements.Show me the data structures
Learn and implement basic algorithms such as searching and sorting on different data structures and examine the efficiency of these algorithms. Use recursion to implement these algorithms and then learn how some of these algorithms can be implemented without recursion. Practice selecting and modifying these algorithms for a variety of interview problems.Problems vs. Algorithms
Build on your algorithm skills by learning more advanced algorithms such as brute-force greedy algorithms, graph algorithms, and dynamic programming which optimizes recursion by storing results to sub problems.Route Planner
Brynn is a former Udacity employee who worked as Lead Data Analyst at Udacity before joining Facebook as Data Engineer. Currently, she is working as software engineer with 10x Genomics.
Abe is a Content Developer at Udacity and previously taught university courses in psychology and computer science. He loves both learning and teaching, and has a particular passion for breaking down difficult concepts and making them easier to master.
Kyle has developed projects for a variety of Udacity's Nanodegree programs, such as Self-Driving Car Engineer, Robotics, and Blockchain. Kyle, a self-taught developer, is always striving towards creating great learning experience for students.
Whether you want to be a web developer, a machine learning engineer, or a data scientist, having a deep understanding of Data Structures and Algorithms is essential to acing job interviews and becoming a successful software engineer. As Linus Torvalds famously said, "Bad programmers worry about the code. Good programmers worry about data structures and their relationships".
The Data Structures and Algorithms Nanodegree program will help you excel at solving everything from well-defined problems, like how to calculate the efficiency of a specific algorithm, to more open-ended problems, like building your own private blockchain or writing a web-crawler.
You’ll work on over 100 exercises and four real-world projects so that you can get the hands-on practice required to learn how to implement appropriate solutions based on your design choices.
While this course is not designed to prepare you for a specific job, after completing this program, you will have had extensive practice solving data structures and algorithm problems to help you prepare for the data structures and algorithms part of coding interviews.
If you are looking to improve your skills in data structures and algorithms -- to prepare for the technical portion of job interviews, to improve your software engineering skills, etc. -- then this Nanodegree program will provide you with extensive practice with defined and open-ended problems so that you learn how to implement the appropriate solution based on your design choices.
This Nanodegree program was a collaboration between Udacity’s content and engineering teams, as well as industry experts.

There is no application. This Nanodegree program accepts everyone, regardless of experience and specific background.
To optimize your chances of success in the Data Structures and Algorithms Nanodegree program, you should have the following knowledge:
Intermediate Python programming
If you are new to programming, we recommend the Introduction to Programming Nanodegree program.
This program consists of one three (3)-month long term. To graduate from the program, you'll need to successfully complete all required projects.
These projects are designed to give you hands-on practice, and enable you to demonstrate your mastery of the concepts.
Each project will be reviewed by the Udacity reviewer network. Feedback will be provided and, if you do not pass the project, you will be asked to resubmit the project until it passes.
Access to this Nanodegree program runs for the period noted in the Term Length section above.
Please see the Udacity Nanodegree program FAQs for policies on enrollment in our programs.
The full program consists of one 3-month long Term at a cost of USD $599. Payment is due before the term begins.
