What is CFHelper?
CFHelper is an advanced solution analysis platform designed specifically for competitive programmers. It helps you learn from the best by analyzing thousands of submissions from Codeforces, identifying exceptional solutions, and providing AI-generated hints to guide your problem-solving approach.
Whether you're preparing for competitions, learning new algorithms, or simply curious about different approaches to a problem, CFHelper provides comprehensive insights that go beyond what's available on Codeforces directly.

How It Works
1. Data Collection: CFHelper fetches problem information and submissions from the Codeforces API, along with scraping problem statements using Firecrawl to bypass anti-bot protection.
2. Smart Analysis: The system analyzes submissions to identify exceptional solutions based on execution time, memory usage, and programmer rating. It selects solutions from highly-rated users to ensure quality.
3. AI Enhancement: Problem statements are sent to Google Gemini AI to generate intelligent hints that guide users without giving away the complete solution.
4. Caching: All results, including hints and problem statements, are cached in MongoDB for instant retrieval, reducing API calls and improving performance.
