What are 2-3 Trees?
Explore the concept of 2-3 trees, a balanced search tree used in data structures. Understand their ordered node properties, balanced height, and how this supports efficient search, insertion, and deletion operations with logarithmic time complexity. The lesson lays a foundation for implementing these operations efficiently in coding interviews.
We'll cover the following...
Introduction
A 2-3 tree is another form of search tree, but it is very different from the binary search tree. Unlike BST, 2-3 tree is a balanced and ordered search tree, which provides a very efficient storage mechanism to guarantee fast operations. In this chapter, you will take a detailed look at 2-3 trees’ structure, the limitations it follows, and how elements are inserted and deleted from it. One key feature of a 2-3 tree is that it remains balanced. It does not matter how many insertions or deletions you perform. The leaf nodes are always present on the same level and are small in number. This is ...
