A plug-and-play class-library project of standard Data Structures and Algorithms, written in C#. It contains 75+ Data Structures and Algorithms, designed as Object-Oriented isolated components. Even though this project started for educational purposes, the implemented Data Structures and Algorithms are standard, efficient, stable and tested.

This project originally started out as an interview preparation project. However, after receiving a great amount of positive responses on reddit, and noticing excitement from a few GitHubers to contribute furthermore to it, the project took on a different meaning. So, I decided to keep maintaining it as a reference for data structures and algorithm implementations in C# as well as my own research side-project under these topics.

This is a C#.NET solution-project, and it contains three subprojects:

1. Algorithms: A class library project. Contains the Algorithms implementations
2. Data Structures: A class library project. Contains the Data Structures implementations
3. UnitTest: Unit-testing project for the Algorithms and Data Structures

1. .NET Core >= 2.0
2. XUnit
