How to Use
This is an educational tool for learning data structures and algorithms through interactive visualizations. 1. Click on any data structure or algorithm from the main menu to open its visualization 2. Use the control buttons (typically "Insert," "Delete," "Find," etc.) to perform operations on the selected data structure 3. Enter values in the input field when prompted for data to add or search 4. Click "Run" or similar buttons to execute operations step-by-step 5. Use playback controls to pause, step forward/backward, or adjust animation speed 6. Watch as the visualization shows how data moves and changes within the structure The tool covers basics like stacks and queues, advanced topics like tree balancing and graph algorithms, plus sorting methods and dynamic programming. Each visualization demonstrates the internal workings of algorithms, showing exactly how data is organized, accessed, and modified. This helps you understand time complexity and implementation details that are difficult to grasp from textbooks alone. Navigate between different data structures using the main menu, and explore both array-based and linked implementations where available.
