Introduction

Welcome to CodePlanet — an intelligent coding practice platform designed to help you master programming through deliberate practice, personalized learning paths, and real-time feedback.

What is CodePlanet?

CodePlanet is more than a problem bank. It's a complete learning ecosystem that:

• Identifies your weaknesses using AI-powered topic analysis
• Tracks meaningful progress beyond just "problems solved"
• Guides your learning with personalized recommendations
• Rewards consistency with streaks, XP, and certificates

Whether you're preparing for coding interviews, competitive programming, or just sharpening your skills, CodePlanet adapts to your learning style.

Why CodePlanet?

🧠 Intelligent Learning

Unlike platforms that throw problems at you randomly, CodePlanet uses weak topic detection to understand where you struggle and creates targeted practice plans.

⚡ Real-Time Feedback

Get instant feedback on your solutions with detailed test case results, runtime analysis, and complexity insights.

🎯 Focused Practice

Our curated problem sets are organized by topic, difficulty, and learning path — so you always know what to practice next.

📊 Meaningful Metrics

Track your actual skill growth, not just problem count. See your improvement across different topics over time.

Who is CodePlanet For?

Key Concepts

Before diving in, here are some concepts you'll encounter:

Problems

Individual coding challenges with test cases. Each problem has:

• Difficulty rating (Easy, Medium, Hard)
• Topic tags (Arrays, Trees, DP, etc.)
• Acceptance rate
• Company tags (for interview prep)

Learning Paths

Curated sequences of problems designed to build skills progressively. Follow a path to go from beginner to expert in a topic.

Weak Topics

Areas where your performance is below your average. CodePlanet automatically detects these and suggests practice problems.

Streaks & XP

Gamification elements to keep you motivated:

• Streaks: Consecutive days of practice
• XP: Points earned for solving problems
• Certificates: Proof of completed learning paths
