## Purpose
Comprehensive collection of educational Go programming examples designed to demonstrate fundamental language features, algorithmic concepts, and concurrency patterns. This directory serves as a learning resource and reference implementation for Go developers, progressing from basic syntax to advanced concurrent programming techniques.
## Key Components
### Basic Language Demonstrations
- **hello_world.go**: Standalone Hello World example showcasing basic function definition, string formatting, and console output patterns
- **hello_world/**: Extended educational example with comprehensive Go language feature demonstration, specifically designed for MCP Debugger tool integration
### Algorithmic Examples
- **fibonacci.go**: Simple recursive Fibonacci implementation demonstrating basic algorithmic concepts with console output
- **fibonacci/**: Advanced algorithmic complexity analysis comparing three Fibonacci implementations (recursive O(2^n), iterative O(n), and memoized O(n)) with performance benchmarking
### Concurrency Patterns
- **goroutines/**: Comprehensive concurrent programming tutorial demonstrating goroutine creation, channel communication, worker pools, and synchronization techniques using `sync.WaitGroup`
## Public API Surface
Each component provides executable entry points through standard Go `main()` functions:
- **Single-file examples**: Direct execution via `go run filename.go`
- **Directory-based examples**: Execution via `go run main.go` from respective subdirectories
- **Educational interfaces**: Programs designed for observation and learning rather than library integration
## Internal Organization and Data Flow
The examples follow a pedagogical progression from foundational to advanced concepts:
1. **Language Basics**: Hello World examples establish fundamental Go syntax, function definition, and I/O operations
2. **Algorithmic Thinking**: Fibonacci implementations demonstrate performance analysis and optimization techniques
3. **Concurrent Programming**: Goroutine examples showcase parallel processing and inter-process communication
Data flows are primarily educational, moving from input demonstration through processing examples to formatted console output for learning observation.
## Important Patterns and Conventions
- **Educational Structure**: All examples prioritize clarity and learning over production efficiency
- **Progressive Complexity**: Components build from simple concepts to sophisticated implementations
- **Standard Library Focus**: Minimal external dependencies, relying primarily on Go's standard library (`fmt`, `sync`, `time`)
- **Self-Contained Design**: Each example can be studied and executed independently
- **Performance Awareness**: Advanced examples include benchmarking and complexity analysis for educational comparison
- **Concurrency Safety**: Goroutine examples demonstrate proper synchronization and resource management patterns
## Dependencies
- **Core**: `fmt` package for formatted I/O across all examples
- **Concurrency**: `sync` package for goroutine coordination and `time` package for work simulation
- **Target Audience**: Designed for Go language learners, algorithm students, and developers exploring concurrent programming patterns
