In computer sciencea 2—3 tree is a tree data structurewhere 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 tree. We say that an internal node is a 2-node if it has one data element and two children.

We say that an internal node is a 3-node if it has two data elements and three children.

We say that T is a 2—3 tree if and only if one of the following statements hold:. Searching for an item in a 2—3 tree is similar to searching for an wstructura in a binary search tree.

Since the data elements in each node are ordered, a search function will be directed to the correct subtree and eventually to the correct node which contains the item. Insertion works by searching for the proper location of the key and adding it there.

If the node becomes a 4-node then the node is split into two 2-nodes and the middle key is moved up to the parent. The diagram illustrates the estructtura.
