Web-wide most detailed Java implementation of single-chain list (add, delete, change, check, traverse, etc.) Take the student management system as an example: the node is the student, and the whole chain table is the management system Node Definition, Constructor The student class has information such as number, name, subscript, etc. By defa ...

There are two minimum spanning tree algorithms. One is prim algorithm and the other is Kruskal algorithm. The time complexity of the two algorithms are o (n^2) and O (mlogn) [n is the number of points and m is the number of edges]. The two algorithms behave differently in different graphs. Let's start with prim algorithm. The core idea of thi ...

Introduction to JAVA array (I) So far, the basic syntax of java has been basically summarized. The next thing to learn is array. 1. Overview of Array Array is a collection of multiple data of the same type arranged in a certain order, named with a name, and managed uniformly by numbering.Common concepts of arrays: 1. Array name 2. Elements 3 ...

1, Curriculum system Concept Sequence table, single chain table, one-way circular table, two-way circular table, queue, stack Tree Figure Algorithm: Search algorithm 2, Why learn data structures 1. Program = data structure + algorithm Data structure is not only a very important thing to write code, but also a basic course 2. Data stru ...

Comparison of java objects Objectives of this section Raising questionsComparison of elementsComparison of objects in JavaComparison method of PriorityQueue in collection frameworkSimulate the implementation of PriorityQueue 1. Questions raised Last class, we talked about priority queue. When inserting elements into priority queue, there is ...

Backtracking algorithm is actually a similar exhaustive search attempt process, which is mainly to find the order of the problem in the search attempt process. When it is found that the solution conditions are not met, it will "backtrack" (i.e. backtrack) and try other paths. Therefore, backtracking method is known as "common pro ...

Some codes involve the knowledge mentioned before Quick sort Two way fast platoon Improve according to the one-way fast sorting in the previous section. In order to prevent each cycle, the same number is on one side, such as: 3 4 1 2 3 2 1 3 1 3 5 4 Single way fast platoon: 1 1 2 1 3 3 3 4 5 4 In this way, the case equal to thre ...

Change The most direct solution to the change problem is the greedy strategy. For example: for coins with face values of 1, 5, 10 and 25, solve the minimum number of coins required to exchange 63 yuan. The idea of greedy strategy is to constantly use the coins with the largest face value to try. No, in this case, 25 coins are used to try the ...

Research on consistent HASH algorithm Contributor: underground Stalker 1. Introduction When studying the CRUSH algorithm of distributed storage Ceph, I saw the article introduce that it is a special consistency HASH algorithm, so I began to study the consistency HASH algorithm, make early preparation, and found that the concept is indeed clo ...

Today, let's talk about monotonic queues and stacks. Although these two data structures are not directly implemented in c + + stl, it is easy to use monotonic queue (stack) in the process of doing questions, especially in some difficult questions. Monotone queue 1.1 introduction to monotone queue Monotonic queue is the monotonous relati ...
