A 2-3 Tree is a specific form of a B tree. A 2-3 tree is a search tree. However, it is very different from a binary search tree.
And the right link points to all, 2-3 tree containing all the keys that are larger than the larger of the two keys in the 3-node. Okay, let's take a look at a demo of searching in a 2-3 tree. So say we have this 2-3 tree here and we want to search for whether or not H is one of the keys in the tree. AVL Trees 3 Binary Search Tree - Best Time. All BST operations are O(d), where d is tree depth. minimum d is for a binary tree with N nodes. 2 0 1 3 0 6 4 9 1 5 8 1 height of node = h balance factor = h left-h right empty height = -1 1 0 2 0 6 4 9 1 5 1 0 7 0 7 balance factor 1-(-1) = 2-1 Tree A (AVL) Tree.
Here are the properties of a 2-3 tree:
- each node has either one value or two value
- a node with one value is either a leaf node or has exactly two children (non-null). Values in left subtree < value in node < values in right subtree
- a node with two values is either a leaf node or has exactly three children (non-null). Values in left subtree < first value in node < values in middle subtree < second value in node < value in right subtree.
- all leaf nodes are at the same level of the tree

Insertion
The insertion algorithm into a two-three tree is quite different from the insertion algorithm into a binary search tree. In a two-three tree, the algorithm will be as follows: Xojo 2015 2 1 0 – object oriented programming tool.
- If the tree is empty, create a node and put value into the node
- Otherwise find the leaf node where the value belongs.
- If the leaf node has only one value, put the new value into the node
- If the leaf node has more than two values, split the node and promote the median of the three values to parent.
- If the parent then has three values, continue to split and promote, forming a new root node if necessary
