Recent Chinese New Year red envelopes have become a novel trend, as a program ape on the algorithm is more curious than the curiosity of red envelopes, here introduced a kind of random red envelopes of their own thinking, and please advise. Algorithm Introduction One, the amount of red envelopes limit For the micro-

2015 days of cat Taobao activities although there is a period of time, but 2015 pairs of 110,000 shops with the celebration of red envelopes have been opened Oh, 2015 days of cat Taobao million shop with the red envelopes can only participate in the mobile phone clients Oh, if you do not know 2015 double 11 How to rob Red envelopes, The following Pepsi net small

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

Red routes how to help you manage your product follow-up plan (products backlog) In most development methodologies, there is always a consultation around what is needed to be developed first. For example, scrum (rapid development method), its product owners and teams in each of the secondary sprint, the concept and use of scrum and sprint, you can see "in the Smoke of scrum and XP"), The core issue is to negotiate which follow-up project will become

What is a red and black tree??? The red and black tree is first a search binary tree, each node in the tree color is not black or red. It has the following characteristics:1, the root node is black2. Each knot is either black or red.3. Cannot have two consecutive red nodes .

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 to solve a non-equilibrium tree, which is a t

The requirement is this: Now the company regularly send red envelopes, 1 times a week Background Each period will be setFor example, 1 yuan of red Envelopes 10 2 yuan of 100 88 yuan of 10 There's a total number of red envelopes for each issue, like now I'm talking about the 3rd issue, the total number of red envelopes

About red and black treesRed-black tree is a self-balancing binary search tree, also has the characteristics of a two-fork tree, keeping the right side is always greater than the left node key features. The AVL tree mentioned earlier is also a variant of the binary search tree, which does not reach the height of the AVL tree, in other words, its height is not as high as the AVL tree, but his application is more extensive, and in practice it is quite e

Web design is important, whether it is color collocation or not color collocation, should pay attention to. Next we start to analyze each color, and we first explore the use of the red line in web design. As we all know, red is a very strong emotional color, can make people feel excited, so we China will also think Red is a kind of festive color, will bring peop

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/black tree, I must write it well to make readers fully understa

The previous article introduced the 2-3 lookup tree, you can see that the 2-3 find tree can ensure that after inserting elements can maintain the balance of the tree, the worst case is all the child nodes are 2-node, the height of the tree is lgn, thus guaranteeing the worst case of time Complexity. however, 2-3 trees are more complex to implement, this paper introduces a simple implementation of 2-3 tree data structure, that is, red-black trees (

Summary Bowen explores four key points: 1, a brief introduction to the red-black tree; 2, red-Black tree node data structure; 3, the color of the parent pointer field and the node of the red-black tree node are organically combined; 4. Defines the interface between the red-black tree and the operator tree node pointer

Jingdong Mall 618 Crazy Shop, the days of the cat on this side can not go on, and immediately opened the days of the cat year, have to say Alibaba really rich. As a buyer, we will watch the cat and Dog War, and rob a red envelope, buy something. Small compilation teaches everybody how to rob red envelopes in the day cat. The days of the cat in the year to promote---from May 25 onwards, lasted up to

Red-green Towers time limit/test 2 seconds memory limit per test 256 megabytes input standard input output standard Output There are r red and G green blocks for construction of the Red-green tower. Red-green Tower can be built following next Rules:red-green tower is consisting of some number of levels; Let the

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 bl

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 exceed 2log (n).The Red-black tree is a two-for

The red and black trees (red-black tree) are one of many balanced search trees, so the time complexity of basic operations (query, delete, search) and so on in the worst case is O (LGN).13.1 The nature of red and black treesThe red and black tree is a binary search tree, and an attribute is added to each node to indica

360 mobile phone assistant in 2016 spring period for users to bring 360 million cash red envelopes, every day can receive red envelopes, in addition to the Spring Festival red envelopes activities and shake a shake, there is a password to enter red envelopes password Oh! 　　360 Mobile phone Assistant 2.1-14

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

It's still the same, first of all: Property 1. nodes are red or black Nature 2. The root is black Nature 3. All leaves are black (leaves are nil nodes) Nature 4. If a node is red, its two sons are black 5. All simple paths from any node to its leaves contain the same number of black nodes. We define: We can see from the deletion of the binary search tree, the last deleted node must be a node with only one
