2 3 Tree Insertion Walkthrough C About 2 3 Tree 2 3 tree is a tree data structure where every node with children internal node has either two children 2 node and one data element or three children 3 nodes and two data elements According to Knuth a B tree of order 3 is a 2 3 tree Nodes on the outside of the tree leaf nodes have no children and one or two data

2 3 Trees 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 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 12 5 1 2 3 Trees This section presents a data structure called the 2 3 tree The 2 3 tree is not a binary tree but instead its shape obeys the following definition A node contains one or two keys Every internal node has either two children if it contains one key or three children if it contains two keys Hence the name

Insertion in 2 3 Trees is a lot different from Binary Search Trees In 2 3 Trees values are only inserted at leaf nodes based on certain conditions As discussed before the insertion algorithm takes O L o g n O Logn O L o g n time where n is the number of nodes in the tree Searching an element is done in L o g n Log n L o g n and Insertion in 2 3 trees is different from binary search trees In 2 3 trees values are only inserted at leaf nodes based on certain conditions As discussed before the insertion algorithm takes O Logn O Logn time where n is the number of nodes in the tree Searching an element is done in Log n Log n and then insertion takes a constant
In this video I am giving you a brief introduction to 2 3 trees followed by an example of insertion into an empty 2 3 tree Two Three trees are extremely us Properties of 2 3 Trees A 2 3 tree follows the below mentioned properties Every internal node in the tree is a 2 node or a 3 node i e it has either one value or two values A node with one value is either a leaf node or has exactly two children Values in left sub tree value in node values in right sub tree
