quicksort algorithm with example in data structure

A brief introduction to the list of why linear lists are neededOf course, in order to overcome the shortcomings of the order table, in the Order table, do insert and delete operations, the need for a large number of moving elements, resulting in efficiency degradation.Classification of linear lists Follow the link method: By implementation angle: The creation of linear linked lists and the idea of simple traversal algorithmCreate a linked list and make a simple traversal of the

replaced and then returned.If not found, the newly added value is placed in the new bucket, and when the free space is insufficient, the capacity is expanded (Resize) and then hashed to the target bucket. It is important to note that the resize operation consumes more resources.SummaryIn the previous articles, we introduced sequential lookups based on unordered lists, binary lookups based on ordered arrays, balanced search trees, and red-black trees, this article finally introduced the last kin

line printer, they are arranged in the order in which they arrive. Therefore, the job being sent to a line printer is basically placed in a queue. This example is about the computer network. Use many of the PC's network settings, where the disk is placed on a machine called a file server. A user using a different computer accesses a file on a first-come-first-served basis, so its data

understand the Kruskal algorithm from another angle: in the initial stage, n vertices in the graph are considered as independent n connected components. From the tree perspective, N root nodes. The edge selection standard is as follows: if the two vertices on the edge belong to two different connected components, this edge can be used; otherwise, the edge with the smallest weight is considered. So the question comes again. How can we determine whethe

The 1th Chapter when we talk about algorithms, what are we talking about? whether it's bat or flag, any kind of technical company with a bit of skill, interviewing is an algorithm. Why is the algorithm so important? Do you really use algorithms at work? What is the use of the algorithm? What are we talking about when we talk about algorithms? 2nd Chapter The basi

, select the first "real Exchange", the sequence becomes 1, 4,3,2,5, which means that this exchange makes the number of reverse order of the sequence-7. So choosing a sort can use less "real swapping" to complete the sorting, which does not mean that the choice of sorting will be quick, for reasons not to repeat.Next, according to the preceding theorem (3, 5, 6). We can introduce the last theorem in this article, that is, the reasoning of Theorem 7, and the fundamental of all advanced sorting al

Hash table of Data Structure and algorithm 07 A hash table is also called a hash table. It is a data structure directly accessed based on the key value. That is to say, It maps the keyword value to a location to access records to speed up the search. This ing function is cal

I recently studied the book "big talk Data Structure". I used to think that I understood it and thought I understood it. In fact, it is not. When I really want to close the book and write it on my own, I found that I still don't know, so in this learning process, in order to achieve better results, every time I understand a certainAlgorithmThen close the book, implement it by yourself, and summarize the ide

Recently heard that the data structure and algorithm practice teacher again out of the same topic as the previous year, can not help but think of the last time I finished homework when the point drops, regret at that time did not write the habit of blogging, some of the previous experience this year the past also gradually forgotten, suddenly have a summary of th

Origin: Computer technology in the future will be very important, so want to do some training in the amateur things, before the company has also done training programming things, have this experience. And the importance of data structure and algorithm is self-evident.The programming language chooses Python, starts quickly, learns the

The previous articles introduced basic sorting algorithms, and sorting is usually a prelude to finding. Starting from this article, the basic lookup algorithm is introduced. In the introduction of the search algorithm, first of all need to understand the symbolic table of the abstract data structure, this article firs

Algorithm-Summary of Basic Data Structure In fact, the data structure and algorithms are really important, and they have never been very concerned about before, so every written test interview is despised. "Programming is the algorithm
