- C++: Multiple subdirectories providing solutions for problems on classes, pointers, strings, attribute parsing, and variable-sized arrays.
- Java: Solutions such as string manipulation and log-level parsing.
- Data Structures: Foundational problems and explanations.
- Certifications: Solutions and documentation for HackerRank certification challenges (e.g., REST API: Patient's Medical Record).
Special focus is given to certification problems such as:
- REST API: Patient's Medical Record
- Solve API-based data tasks, calculate averages, handle pagination, and parse JSON responses.
- Sample inputs, outputs, and explanations available in Certifications/REST API Patient's Medical Record/README.md.
- Browse by Language or Topic: Navigate to the relevant folder based on the programming language or HackerRank category.
- Read Documentation: Many folders contain a
README.mdfile with additional details about the problems and solutions. - Run and Experiment: Use the code as reference for your own HackerRank submissions or practice.
Contributions are welcome! If you have solutions to additional HackerRank problems, improvements to existing code, or new documentation:
- Fork the repository
- Add your solution or edit existing files
- Open a pull request with a description of your changes
