in 2-3-4 Trees Time complexity: • A search visits O(log N) nodes • An insertion requires O(log N) node splits • Each node split takes constant time • Hence, operationsSearch and Insert each take time O(log N) Notes: • Instead of doing splits top-down, we can perform them bottom-up starting at the in-sertion node, and only when needed.

2-3-4 Trees. Our next self-balancing tree is called a 2-3-4 tree (or a B-tree of order 4), so called because nodes can have anywhere from two to four children. Regular binary search trees can't always be perfectly balanced - that's why AVL trees have to allow the flexibility that subtree heights can differ by at most 1. But because 2-3-4 trees allow nodes to have 2, 3, or 4 …

### (2,4) TREES - Purdue University

In computer science, a 2–3–4 tree (also called a 2–4 tree) is a self-balancing data structure that can be used to implement dictionaries. The numbers mean a tree where every node with children (internal node) has either two, three, or four child nodes: • a 2-node has one data element, and if internal has two child nodes; • a 3-node has two data elements, and if internal has three child nodes;

(2,4) Trees 5 (2,4) Insertion • Always maintain depth condition • Add elements only to existing nodes • What if that makes a node too big? - overﬂow • Must perform asplit operation - replace node with two nodes and - gets the ﬁrst two keys - gets the last key - send the other key up the tree - if is root, create new root with third key
