From coolshell (from a website: data structure visualizations) Do you still remember the previous article about visual sorting? On the Internet, I saw a home page for various visual data structures and basic algorithms by David galles from the University of San Francisco. The website is here for you to see. I listed t

Stacks and queuesStack (last in, first out)Stack, which allows access to only one data item: The last inserted data item.Stacks can be used to check the matching problems of parentheses and parse mathematical expressions, similar to those used in the compilation principle.The operation of the picture is actually summed up: 1. Read the left delimiter into the stack, 2. The right delimiter is read to match th

) + (N-2) +...+1 = N (N-1)/2When the value of N is very large, the algorithm compares the number of N2/2 times, ignoring minus 1.Assuming that the data is random, it is possible to swap locations each time, possibly without swapping, assuming a probability of 50%, then the number of interchanges is N2/4. However, if the worst-case scenario is that the initial data is reversed, the position is swapped for ea

node without any child nodes.The number of layers in the two-ary tree is L, and the node points are N, then N=2L-1;L=LOG2 (n+1).5. Complete binary TreeConcept: In addition to the last layer, each of the other layers of the number of nodes are full, the last layer if also full, is a full two fork tree, is also a complete binary tree. If the last layer is dissatisfied, the missing nodes are all concentrated on the right, and that is a tree full of two forks.As below, are completely binary tree!!!

Linked List of data structures and algorithms Classification of linked lists: (1) single-chain table Header insertion: you only need to maintain one header node, which is often used to simulate the stack; Tail insertion: You need to maintain the head and end nodes, which are often used to simulate queues. (2) Two-way linked list Bidirectional traversal can be use

Array of data structures and algorithms The basic concept of array: array is the simplest and most commonly used data structure, but there are also some considerations: (1) array allocation method and storage location; (2) initialization; (3) Advanced definition of arrays in different languages; (4) multi-dimensional a

Leave the machine and languageAlgorithmIt's boring, just like leaving the data structure to talk about algorithms. Computers in the X86 architecture are machines, while those in SharePoint are also machines. 8. Queen's solution is an algorithm. Integrating Bi applications on the portal homepage is also an algorithm-an algorithm for Sharepoint's "machine. You can use C and LISP to write the 8 Queen's algor
