Structure

The project is structured into two main directories:

LeetCode.Solutions

This directory contains my solutions to LeetCode problems, categorized by difficulty:

• Easy: Solutions to easy problems.
• Medium: Solutions to medium problems.
• Hard: Solutions to hard problems.

Each subdirectory contains individual C# files with solution implementations. 📁

LeetCode.Tests

This directory contains corresponding unit tests for each solution, also organized by difficulty:

• Easy: Tests for easy problems.
• Medium: Tests for medium problems.
• Hard: Tests for hard problems.

Each subdirectory contains unit test files written using xUnit framework to test the solutions in the LeetCode.Solutions directory. 🧪

Getting Started

To get started with the LeetCode Solutions project, follow these steps:

Prerequisites

Make sure you have the following installed:

• .NET SDK for running the project and tests.

Setup

1. Clone this repository to your local machine:

   git clone https://github.com/SergeyUrvantsev/LeetCodeSolutions-CSharp.git
   cd LeetCode

2. Navigate to the test project and add a reference to the solutions project:

   cd LeetCode.Tests
   dotnet add reference ../LeetCode.Solutions/LeetCode.Solutions.csproj

Now you're ready to explore the solutions and tests or add your own contributions! 🎉

Usage

The LeetCode Solutions project can be used for several purposes:

Exploring Solutions

Feel free to explore the solutions provided in the LeetCode.Solutions directory. Each solution is categorized by difficulty level, making it easy to find solutions to specific types of problems.

Running Tests

You can run the unit tests provided in the LeetCode.Tests directory to verify the correctness of the solutions. Navigate to the LeetCode.Tests directory and execute the following command:

cd LeetCode.Tests
dotnet test

Workflows

dotnet.yml

The dotnet.yml file in the .github/workflows directory contains the GitHub Actions workflow configuration for building and testing the project. This workflow runs on every push to the main branch and every pull request into the main branch. It performs the following tasks:

• Restores dependencies for the LeetCode.Solutions project.
• Restores dependencies for the LeetCode.Tests project.
• Builds the LeetCode.Solutions project in Release configuration.
• Runs the tests for the LeetCode.Tests project in Release configuration.

For more information, please refer to the dotnet.yml file.
