Cardio — Algorithms & Data Structures

Cardio is a personal learning project focused on exploring classic and modern algorithms and data structures, implemented from scratch in multiple programming languages.

This repository serves as both a learning log and a practical reference for how core concepts are expressed across different ecosystems.

Current Implementations

Language	Status	Location	Testing
C / C++	✅ Active	/cpp	Unit tests with Google Test
.NET / .NET Core	✅ Active	/dotnet	xUnit test suite
PHP	🕐 (coming soon)	/php	TBD
Java	🕐 (coming soon)	/java	JUnit (planned)

Project Goals

• Learn and reinforce algorithmic thinking through practical coding.
• Compare performance and syntax differences between languages.
• Build a reusable collection of algorithm implementations for reference and practice.
• Automate build and test pipelines for each language.

Folder Structure

.cardio/
├── cpp/           # C/C++ implementation + tests
├── dotnet/        # .NET implementation + xUnit tests
├── php/           # (coming soon)
├── java/          # (coming soon)

Running Tests

Each language folder includes its own build and test instructions.

C/C++

cd cpp
cmake .
make
./tests/runTests

.NET

cd dotnet
dotnet test

Contributing

Contributions are welcome! You can help improve Cardio by:
