LeetCodeVisual

Master algorithms visually through interactive learning experiences

Our Mission

LeetCodeVisual is an interactive educational platform designed to help developers understand and master data structures and algorithms through visual learning. We believe that complex algorithmic concepts become clearer when you can see them in action, step-by-step, rather than just reading code or descriptions.

Our platform bridges the gap between theoretical algorithm knowledge and practical coding interview preparation by providing animated visualizations of real LeetCode problems, complete with detailed explanations of multiple solution approaches.

How It Works

👁️

Visual Learning

Watch algorithms execute step-by-step with interactive visualizations that highlight data structures, operations, and state changes in real-time.

📚

Detailed Explanations

Understand the intuition and reasoning behind each solution approach with clear explanations, pseudocode, and complexity analysis.

💻

Real Challenges

Practice with actual LeetCode problems commonly asked in technical interviews at top tech companies.

Key Features

  • ✓Multiple Solution Approaches: Compare brute-force, optimized, and advanced solutions for each challenge
  • ✓Interactive Animations: Control animation speed and step through solutions at your own pace
  • ✓Complexity Analysis: Learn time and space complexity for each approach
  • ✓Challenge Categories: Browse problems by topic (Arrays, Hash Tables, Two Pointers, Sorting, etc.)
  • ✓Dark Mode Design: Optimized for extended learning sessions with WCAG AAA contrast standards

Built With Modern Technologies

Frontend

  • • Next.js 16 (App Router)
  • • React 19
  • • TypeScript 5.9
  • • Tailwind CSS 4

UI Components

  • • Radix UI (accessible primitives)
  • • Custom visualization components
  • • Material Design elevation system
  • • CSS custom properties

Architecture: The platform uses a modular challenge factory system with separated metadata, descriptions, and solution steps for maintainability and scalability.
