I. OverviewIn the previous article, we reviewed the characteristics of red-black tree and added processing, we can learn that the red and black tree is a binary search tree, on the basis of the increase in the color of the node constraints to make the red and black trees approximate balance. When we add or remove nodes, we need to adjust the tree so that it satis

(The learning references are mainly introduction to algorithms.) The first is the nature of the red and black trees. A binary search tree is a red-black tree that meets the following requirements. 1) each node is either red or black. 2) The root node is black. 3) each leaf node (NIL) is

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 bit and path at each node. The following summar

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.3. All null junctions are called leaf nodes, and the color is considered black . 4

Finally, we will explore the red and black tree deletion algorithm, compared to the insertion operation, it is more complex situation. So it's easy to get into the south wall, we need to use the idea of conversion and transformation (remember the four ways of thinking in high school math, as applicable here), by raising the change, the red black tree mapped into a b- tree, and stand in the latter angle, in

1. OverviewRed black tree is a self-balancing binary lookup tree, similar to the red black tree and the AVL tree, which maintains the balance of the binary lookup tree with specific actions when inserting and deleting operations, resulting in higher lookup performance.Although it is complex, its worst-case run time is also very good, and is efficient in practice: it can be found, inserted and deleted in O (

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 executing on the linked list. So we need to build

Before we learn binary search tree when hair now in some cases its height is not very uniform, and sometimes degenerate into a long chain, so we quoted 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 the color bits and paths on each node. The following summarizes the nature of the red

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.

The two-fork search tree is described earlier, and he has no problem with the efficiency of finding and inserting in most cases, but he is less efficient in the worst case. The data structure of the balanced lookup tree introduced in this article and later in this article ensures that the LGN efficiency can be achieved in the worst case, and we need to make sure that the tree remains in equilibrium after the insert is complete, which is the Balanced search tree. In a tree with n nodes, we want t

The root node is blackNature 3. All leaves are black (leaves are nil nodes)Nature 4. If a node is red, its two sons are black. (That i
