Recursion Visualizer

This visualizer helps you see recursion in action.

1️⃣ Build

Creates the recursion tree and prepares all calls.

2️⃣ Play

Runs recursion automatically from start to finish.

3️⃣ Step ⭐

Executes one call or return at a time. Best for learning.

🌳 Recursion Tree

Shows which function calls which. Highlighted node = active call.

📚 Call Stack

Shows how functions are stacked in memory.

🧾 Trace

Text log of calls (→) and returns (←).

Tip: Start with Factorial, n = 4 and use Step.

Recursion is just a function trusting itself.
