Languages & Topics Covered

• 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).

---

Certifications

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.
