## Data Structures & Algorithms

In this course you will learn data structures and algorithms by solving 80+ practice problems. You will begin each course by learning to solve defined problems related to a particular data structure and algorithm. By the end of each course, you would be able to evaluate and assess different data structures and algorithms for any open-ended problem and implement a solution based on your design choices.

Learn data structures and algorithms by solving 100+ practice problems.

###### Prerequisite Knowledge

Python & Basic Algebra.See detailed requirements.

• #### Introduction

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
• #### Data Structures

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
• #### Basic Algorithms

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.

#### Program Details

##### PROGRAM OVERVIEW - WHY SHOULD I TAKE THIS PROGRAM?
• ###### Why should I enroll?
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 80 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.
• ###### What jobs will this program prepare me for?
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.
• ###### How do I know if this program is right for me?
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.
• ###### Who built this Nanodegree program?
This Nanodegree program was a collaboration between Udacity’s content and engineering teams, as well as industry experts.
• Mat Leonard, Product Lead, School of AI at Udacity

Instructors
• Brynn Claypoole, Software Engineer at 10x Genomics
• Kyle Stewart Frantz, Content Developer at Udacity
• Abe Feinberg, Content Developer at Udacity

Other Udacity Contributors:
• Dane Hammer, Robin Robin, James Bibby, Pradeep Uppala, Brok Bucholtz, Cezanne Camacho, Alan Anderson, Peiyan, David Harris, Stephen Welch, and Chris Gearhart
• ###### Do I need to apply? What are the admission criteria?
There is no application. This Nanodegree program accepts everyone, regardless of experience and specific background.
• ###### What are the prerequisites for enrollment?
To optimize your chances of success in the Data Structures and Algorithms Nanodegree program, you should have the following knowledge:
• Intermediate Python programming

• Basic algebra
• ###### If I do not meet the requirements to enroll, what should I do?
If you are new to programming, we recommend the Introduction to Programming Nanodegree program.
##### Tuition and Term of Program
• ###### How is this Nanodegree program structured?
The Data Structures and Algorithms Nanodegree program is comprised of content and curriculum to support four (4) projects. We estimate that students can complete the program in four (4) months working 10 hours per week.
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.
• ###### How long is this Nanodegree program?
Access to this Nanodegree program runs for the length of time specified in the payment card above. If you do not graduate within that time period, you will continue learning with month to month payments.
