Each course section is represented as a separate namespace. Only the lessons that included any significant coding were included in this repo.\n\nClass name formats are:\n- For course lessons: *Lesson + lesson_number + lesson_name* (e.g. `Lesson26BigOAndScalability.cs`)\n- For course lessons with multiple exercises: *Lesson + lesson_number + exercise_name* (e.g. `Lesson72TwoSum.cs`)\n\n### Prerequisites\n\nThis project is compatible with .NET Standard 2.0 (compatible packages [here](https://docs.microsoft.com/en-us/dotnet/standard/net-standard#net-implementation-support). To download the .NET SDK's visit [this page](https://dotnet.microsoft.com/download). By default the project is configured to target .NET Core 2.1.\n\nTo change the targeted framework, just set the `\u003cTargetFramework\u003e` tag in *DataStructuresAndAlgorithms.csproj* to appropriate value.\n\nE.G. to target the .NET Framework 4.7.1 change the tag value to:\n\n```wsdl\n\u003cTargetFramework\u003enet471\u003c/TargetFramework\u003e\n```\n\n### Installing\n\nSimply clone the repository to your local machine and run the project. It's really that simple!\n\nTo run a specific lesson example go to *Program.cs* and swap the lesson class to the desired one and run the application.\n\nExample for running *Lesson 76. - Hash Collisions*:\n```csharp\nstatic void Main(string[] args)\n{\n    var lesson = new Lesson76HashCollisions();\n    lesson.Run();\n}\n```\n\nConsole output:\n```\n54\nabra kadabra\nahhhhhh!\n```\n\n## Contributing\n\nPlease read [CONTRIBUTING.md](CONTRIBUTING.md) for details on our code of conduct, and the process for submitting pull requests to the project.\n\n## Authors\n\n* **Nenad Misic** - *Initial work* - [misicnenad](https://github.com/misicnenad)\n\n## License\n\nThis project is licensed under the MIT License - see the [LICENSE.md](LICENSE.md) file for details\n\n## Acknowledgments\n\n* Big thanks to [aneagoie](https://github.com/aneagoie/) for creating the Udemy course!\n* The course can be found [here](https://www.udemy.com/course/master-the-coding-interview-data-structures-algorithms/)\n* Hat tip to [PurpleBooth](https://gist.github.com/PurpleBooth) for awesome [README.md](https://github.com/PurpleBooth/a-good-readme-template) and [CONTRIBUTING.md](https://github.com/PurpleBooth/a-good-readme-template/blob/main/CONTRIBUTING.md) templates\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2F0xneshi%2Fdata-structures-and-algorithms","html_url":"https://awesome.ecosyste.ms/projects/github.com%2F0xneshi%2Fdata-structures-and-algorithms","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2F0xneshi%2Fdata-structures-and-algorithms/lists"}
