I. Red/black tree Overview Similar to the AVL tree we have learned before, the red and black trees maintain a balance between the binary search trees through specific operations during insertion and deletion operations to achieve high search performance. However, since the emergence of the red and black trees, the AVL tree has been put in the museum. It is said t

I. Characteristics of red and black trees1. The node can only be red or black.2. The root node is black.3. Leaf node (NIL) is black.4. The child node of the red node must be a black node.5. The path to the descendant nodes of any node that reaches the node contains the same

1. Red and black tree (Red-black trees) Introduction:The Red-black tree (RBT) can be said to be a non-strict balanced version of the Binary-search tree. Correspondingly, the Balanced binary tree (Balanced binary trees) is also called the AVL tree (because it is g.m. The tree Adelson-velsky and E.M Landis invented in 1962 is a strictly balanced version of Binary-s

Deleting a node can also change the balance of the tree, and the imbalance caused by the deletion is more complex than the balance correction caused by the insertion. Simplification is a common method in algorithm analysis. Below we will want to delete the node into three main categories: to delete the node as a leaf node, to delete a node only one child node and to delete has two child nodes. There are two possible colors for deleting nodes, and they need to be treated separately. To simp

A red-black tree is a binary lookup tree, but adds a storage bit to the node's color at each node, either red or black. The red-black tree ensures that no path will be twice times longer than the other paths, and thus is nearly balanced, by limiting the shading of any one path from root to leaf. This chapter mainly introduces the nature, rotation, insertion and d

A red-black tree is a two-prong search tree with color attributes for each node, with a color of red or black. In addition to the general requirements of the binary search tree, we have added the following additional requirements for any valid red-black tree:Nature 1. The nodes are red or black.Nature 2. The root is black.Nature 3. All leaves are

Two forks The basic operation of the search tree can be done within O (h), however the height of the number is higher, and may not be faster than executing on the linked list. red and black trees are a guarantee in the search tree of the worst case time complexity O (LG (n))The nature of red and black trees Each node is either red or black.
