Every solution is written in **C#** and aims for clarity as well as correctness.\n\n---\n\n## 🗂️ Repository Structure\n\nSolutions are split into three folders by difficulty tier:\n\n### 🟢 Easy Section\n\n\u003e Foundational problems focusing on core logic, basic data manipulation, and simple algorithms — ideal for warming up and building confidence with a new problem domain.\n\n📁 [Browse Easy →](./%5BEASY%20SECTION%5D)\n\n---\n\n### 🟡 Medium Section\n\n\u003e A step up in complexity — problems here require more deliberate thinking around data structures, iteration strategies, and combining multiple concepts together.\n\n📁 [Browse Medium →](./%5BMEDIUM%20SECTION%5D)\n\n---\n\n### 🔴 Hard Section\n\n\u003e The tough stuff. Problems that demand algorithmic insight, careful edge-case handling, and efficient solutions.\n\n📁 [Browse Hard →](./%5BHARD%20SECTION%5D)\n\n---\n\n## 💡 What is dCoder?\n\n[dCoder](https://dcoder.tech) is a competitive coding and mobile IDE platform supporting 50+ programming languages. Its **Algo Yo** challenges section features a curated set of algorithm problems with a global leaderboard — designed to test and develop real programming skills through hands-on problem solving.\n\n---\n\n## 🛠️ Tech Stack\n\n- **Language:** C# (.NET)\n- **IDE:** Visual Studio\n- **Platform:** [dCoder Challenges](https://code.dcoder.tech/challenges)\n\n---\n\n## 🚀 Getting Started\n\n1. **Clone the repository**\n   ```bash\n   git clone https://github.com/georgidelchev/dCoder-Challenges.git\n   cd dCoder-Challenges\n   ```\n\n2. **Pick a difficulty tier** and open any `.cs` file in Visual Studio, Rider, or VS Code.\n\n3. **Compare with the original problem** at [code.dcoder.tech/challenges](https://code.dcoder.tech/challenges) to see the full problem statement.\n\n---\n\n## 👤 Author\n\n**Georgi Delchev**\n\n[![GitHub](https://img.shields.io/badge/GitHub-georgidelchev-181717?style=flat-square\u0026logo=github)](https://github.com/georgidelchev)\n[![LinkedIn](https://img.shields.io/badge/LinkedIn-delchevgeorgi-0A66C2?style=flat-square\u0026logo=linkedin)](https://www.linkedin.com/in/delchevgeorgi/)\n[![Facebook](https://img.shields.io/badge/Facebook-georgi.d99-1877F2?style=flat-square\u0026logo=facebook)](https://www.facebook.com/georgi.d99/)\n\n---\n\n## 📄 License\n\nThis project is licensed under the [MIT License](LICENSE).\n\n---\n\n\u003cdiv align=\"center\"\u003e\n\u003csub\u003eMade with ☕ and a love for algorithms\u003c/sub\u003e\n\u003c/div\u003e\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgeorgidelchev%2Fdcoder-challenges","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgeorgidelchev%2Fdcoder-challenges","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgeorgidelchev%2Fdcoder-challenges/lists"}
