Naive Interactive visualization tool for understanding binary search tree algorithms, developed by the University of San Francisco. Ternary Search Tree Visualization Note that the visualization differs from the slides in how it marks complete words by going down one more time and creating an an extra node. It takes advantage of this and will store multiple characters / string of text in an edge instead to reduce the number of extra edges and nodes needed. With this tool, you can efficiently create, visualize, update, and search within a multibit trie using various configurations. A trie is a tree where each edge represents a character and each path from the root node to a leaf spells out a key. R-way tries. Standard tries insert strings by adding nodes for each character. Trie (Prefix Tree)Algorithm Visualizations Key:Algorithm Visualizations Interactive visualization of prefix tree operations. The stop attribute marks if node marks a word (True) or not (False).
