2-3-4 Trees
Explore the fundamentals of 2-3-4 trees, an advanced search tree allowing up to three keys per node and four child nodes. Understand how keys are organized and how this structure improves data management, helping you implement efficient tree operations for coding interviews.
We'll cover the following...
Introduction
2-3-4 is a search tree that is an advanced version of 2-3 trees. This tree can accommodate more keys; hence, there are more child nodes as compared to 2-3 trees. 2-3-4 satisfies all the properties covered in 2-3 trees along with some additional key features:
-
Each internal node can contain three keys at max.
-
Each internal node can have four child nodes at max.
-
In case of three keys at an internal node namely left, mid, and right key, all the keys present at LeftChild node are smaller than the left key, which can be mathematically expressed as:
