Red-black tree is a relatively common data structure in computer science, which makes the search, insertion and deletion of data can maintain the time complexity of O (LGN). However, compared to the general data structure, the implementation of red-black trees has increased the difficulty. The implementation of the red-black tree on the network is voluminous, but

During the Spring Festival, Alipay's "sweep blessing" activities are unusually hot. AR is a kind of new interactive way, compared with traditional marketing method, it can make users deeply participate in interaction and bring new experience to users. and pay Bao red envelopes, pinned to the future of the user's expectations, so its team will consider AR and red envelopes combined to explore a new play. In

Recently took some time to regain the basic knowledge of data structure, first tried the red and black trees, spent most of the month to study its principles and implementation, the following is learned knowledge and some notes sharing. I hope you will advise me. The implementation of this code please click: Red black Tree Implementation codeRed and black tree basic knowledge definitionThe

This blog I will focus on the red-Haishi understanding, highlighting the red-Haishi lookup, here we will discuss the algorithm called top-down insertion, that is, to look down the tree down the insertion pointⅠ, balance trees and non-equilibrium treesBalance tree and non-balanced tree: When inserting a set of data keywords is inserted in ascending or descending order, this is the most extreme of the unbalan

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

Here is a scheme based on Redis to rob red envelopes. The original red envelopes are called Big Red envelopes, and the red envelopes after the split are called small red envelopes. 1. Small red envelopes are generated in advance,

The nature and definition of red and black treesThe Red-black tree is a two-fork search tree that satisfies the following properties:1. Each node is either red or black.2. The root node is black.3. All leaf nodes are black (they are actually null pointers, denoted by nil). Leaf nodes do not contain any keyword information, and all query keywords are on non-endpoi

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

Use PHP to send red envelopes, when we enter the number of red envelopes and the total amount, PHP will be based on these two values to randomly allocate each amount, to ensure that everyone can receive a red envelope, each red envelope amount of money is required to have a difference in the amount of

Red black Tree is a self-balancing binary search tree. Red and black trees are similar to AVL trees in that they maintain the balance of binary lookup trees with specific actions when inserting and deleting operations, resulting in higher lookup performance. Red-black trees can be searched, inserted, and deleted within O (log n) time.Binary search tree can see bi

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 red/black tree maintains a balance between the binary search tree thro

Red-black tree is a very good performance data structure, the key is that it can ensure that the worst performance is also logarithmic, mainly because it is a balanced tree, so also called the balance of the search tree. To understand the red and black trees, it's best to take a look at my previous blog, "Algorithm 4" symbol table and the two-fork lookup tree, to understand the binary lookup tree and why we

Whim to the Alumni Micro-letter group of red Envelopes, I set the total amount of red envelopes for 10 yuan, support 28 people randomly pick up.So an interesting result came up: A has received 0.26 dollarsB received 0.29 dollars.C has received 0.02 yuanD has received 0.56 yuanE has received 0.64 dollars...... What kind of algorithm does the micro-letter use? Simple Baidu, there is no official explanation, j

The so-called red-black tree, is the balanced expansion of the binary search tree, red-black tree and AVL are the balanced version of BST, compared to the full balance of AVL, the red-black tree requires only local balance, so when the red and black trees to insert and delete nodes, the need to adjust less than AVL, st
