LeetCode Solutions in Go

This repository contains my solutions to LeetCode problems, organized by difficulty and implemented in Go with comprehensive testing.

Structure

• problems/: Solutions organized by difficulty (easy/medium/hard)
• cmd/test-runner/: Command-line tool to run specific tests
• pkg/common/: Common data structures and utilities
• .devcontainer/: Docker development environment setup

Usage

Running Tests

# Run all tests
make test

# Run tests for a specific problem
make test-problem PROBLEM=two-sum

# Run with verbose output
make test-verbose

# Run with coverage
make test-cover

Using the Test Runner

# Run all tests for two-sum problem
go run cmd/test-runner/main.go two-sum

# Run specific test case
go run cmd/test-runner/main.go two-sum TestTwoSumHashMap

Debugging in VSCode

1. Open the problem file you want to debug
2. Set breakpoints in your solution code
3. Use Ctrl+Shift+P → "Debug: Start Debugging"
4. Choose "Debug Specific Problem Test"
5. Enter the problem path and test name when prompted

Development Environment

This project uses a devcontainer for consistent development environment:

1. Install Docker and VSCode with Dev Containers extension
2. Open the project in VSCode
3. When prompted, click "Reopen in Container"

Adding New Problems

make new-problem DIFFICULTY=<easy|medium|hard|extra> PROBLEM=<problem name>

where extra is for non leetcode problems.
