🔍 Inspiration

While learning data structures, we realized that understanding how a stack works—especially during recursion—can be abstract and confusing. Visualizing each operation step-by-step makes learning intuitive, especially for beginners. We built StackScope to turn stack concepts into an interactive, visual experience.

⚙️ What it does

StackScope is a web-based tool that allows users to:

• Perform stack operations: Push, Pop, Peek, Clear
• View the middle element dynamically
• Visualize recursive function calls as stack frames (e.g., factorial)
• Watch the stack update in real-time with animated transitions

🛠️ How we built it

• HTML was used to structure the page and input controls.
• CSS handled layout and styling, including highlighting the middle element and styling stack frames.
• JavaScript was used to implement the stack logic, manage recursion, and update the DOM dynamically.
• The recursive visualization was built by simulating a call stack and displaying it as stacked boxes.

🚧 Challenges we ran into

• Making recursion visualization clear and intuitive without overwhelming the UI.
• Keeping the middle element highlighting accurate as the stack changed.
• Ensuring smooth real-time updates for every stack operation without using any frameworks.
• Balancing functionality and simplicity for new learners.

🏆 Accomplishments that we're proud of

• Built a fully functional, beginner-friendly stack visualizer from scratch.
• Implemented recursion visualization in a clean, easy-to-understand format.
• Created a minimal and responsive UI that works well across browsers.
• Successfully merged theory and interaction to aid in data structure learning.

📘 What we learned

• How to implement and manage data structures visually using the DOM.
• How recursion works internally with stack memory.
• Improved our skills in JavaScript, DOM manipulation, and UI design.
• Learned how to break down complex concepts into interactive elements for educational purposes.

🚀 What's next for StackScope

• Add support for more data structures like queues, trees, and graphs.
• Include undo/redo operations and step-through execution.
• Allow users to input their own recursive functions to visualize.
• Add dark mode, animations, and possibly migrate to a React version for scalability.
