Preface:1. Some readers have responded that I have read my previous articles and I still have a thorough understanding of the red and black trees.2. I personally think that, if I use diagrams + code to describe various insertion and deletion situations step by step, they may be more intuitive and easy to understand.3. Since I have written a red/

The red-black tree is a self-balancing binary lookup tree that has the complexity of finding, inserting, and deleting O (log2n) In the worst case scenario. The longest path from the root node to any leaf node in a red-black tree does not exceed twice times the shortest path , so it is an approximate balanced two-fork t

1. What is a red-black tree (1) Introduction In the previous article, we introduced a two-fork search tree with a basic dynamic set operating time complexity of O (h). Unfortunately, these collection operations are faster when the binary search tree height is low, which means that when the height of the tree is high (or even if the tree becomes a 1 chain), the collection operations are not faster than exec

This paper introduces another balanced binary tree: red black tree, which was invented by Rudolf Bayer in 1972. It was called balanced binary B-trees ), leonidas J. change guibas and Robert Sedgewick to a more modern name: The red and black trees. Similar to the AVL Tree mentioned earlier, the

Introduction to Algorithms 13th Chapter Red black TreeRed-Black Trees (red-black tree) are one of many balanced search trees that ensure that the time complexity of basic dynamic set operations is O (LGN) in the worst case scenario.13.1 Nature of

Before we learned the binary search tree, we found that in some cases its height is not very uniform, and sometimes degenerate into a long chain, so we refer to some "balanced" two-fork search tree. The red and black tree is a "balanced" two-fork search tree, which ensures that in the worst case, the time complexity of the basic dynamic set operation is O (NLGN) by attaching some constraints on the color bi

Red and black TreesThe definition of a red-black tree (RBT): It is either an empty tree or a two-fork search tree with a bit of nature:1. The node is not red or black.2. The root node is black
