subtree of the parent node of P.(3) If the left and right subtrees of the deleted node p are not empty, there are two ways: Set PL to the left or right child node of P's parent node Q (depending on p is the left and right child node of its parent node Q), set PR to the right child node of the middle order forward node s of the P node (s is the most right node of PL, which is the largest node in the PL subtree). In order to replace the point of P node with the pre-order or successor

The red and black Tree is a two-fork search tree , which adds a storage bit on each node to represent the color of the node, which can be red or Black.By constraining the height of the tree by any color from the root to the leaf node's simple path, the red-black tree guarant

Red and black tree insert The red-black tree node is inserted by default as the node is red . I understand that, in fact, the insertion of red or black can be, but it is necessary to

Use the java. util. TreeMap source code to understand the red and black trees,Preface This article combines the TreeMap source code of JDK1.6 to explore the mysteries of the Red-black tree. The red/black tree solves the imbalance

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

It has been discussed in the binary tree that if you insert a tree node in random order, the vast majority of them will appear unbalanced. In the worst case, when the data is inserted in order, the binary tree will become a linked list, and the efficiency of insertion and deletion will be severely reduced is the case of inserting a binary tree in ascending order of data: A red-black tree is a way

The red and black trees belong to the balanced binary tree. It is not strictly because it does not strictly control the difference between the left and right subtree height or the number of nodes is less than or equal to 1, but the red black tree height remains the average log (n), and the worst case height will not ex

If the balanced binary tree is a class, then the red-black tree is an example of the class. Algorithm of the book I lost a long time, I can not find, I was based on memory said. The red-black tree algorithm is troublesome, but its thought is very good, if understands its thought also understands its algorithm, I also o

Red-black tree is a more data structure used in engineering, its advantage is that the complexity of the search is O (LgN), and the red-black tree will be inserted in the data to maintain a balance, suppress the complexity of the explosion. Although it is not as efficient as Hashtable, it does not have to plan and allo

Delete operations are more complex than inserts. First, let's look at some of the characteristics of red and black trees. These are my random list, for everyone's reference.1, the red node Father black child must be black. (Nil is a blac
