In this tutorial, we'll look at the insertions and deletions in the 2-3-4 tree. This structure adheres to the BST property, stipulating that every vertex in the left subtree of a given vertex must carry a value smaller than that of the given vertex, and every vertex in the right subtree must carry a value larger. Mention briefly: red-black trees, AVL trees, splay trees, B-trees and other variations.

Though we don't use 2-3-4 trees in practice, we study them to understand the theory behind Red-Black trees. They are often used for what is known as an index — a structure than can be used to efficiently find individual entries in huge data sets. Tree Visualizer is an online platform for creating and customizing rooted binary trees and visualizing common tree traversal algorithms. DSPlot allows you to easily draw trees, graphs (both directed and undirected), and matrices by passing data in primitive form and directly output an image. GitHub is where people build software.
