【自考】数据结构之二叉树遍历
什么是数据结构？ 首先看看维基百科的定义：在计算机科学或信息科学中， 数据结构 （英语：data structure）是计算机中存储、组织数据的方式。通常情况下，精心选择的数据结构可以带来最优效率的算法。 课本中的定义：指一组相互之间存在一种或多种特定关系
什么是数据结构？
首先看看维基百科的定义：在计算机科学或信息科学中，数据结构（英语：data structure）是计算机中存储、组织数据的方式。通常情况下，精心选择的数据结构可以带来最优效率的算法。
课本中的定义：指一组相互之间存在一种或多种特定关系的数据的组织方式和它们在计算机中的存储方式，以及定义在该组数据上的一组操作。
有哪些内容？
直接看图了解数据结构的知识点，如下：
不管是算法还是逻辑结构，都是用数据说话的，所以要先明白了数据的基本概念。大的联系图中已给出，小的知识点需要我们去理解学习。
这篇博客主要讲一个好玩的知识点：喎?http://www.2cto.com/kf/ware/vc/" target="_blank" class="keylink">vcD4KPGgxPrb+subK97HpwPo8L2gxPgo8cD4gICC4xcTu0NS1xNaqyrayu9TZ17jK9qOssru2rrXDv8nS1M/Iv7S/tMrpoaPWsb3Tzai5/dK7tcDM4r2yyP3W1rHpwPooz8jQ8qOs1tDQ8qOsuvPQ8im1xMu8wrehozwvcD4KPHA+ICAgytfPyLi9zbzSu9XFo7o8L3A+CjxwPjxpbWcgc3JjPQ=="http://www.2cto.com/uploadfile/Collfiles/20141010/2014101009203913.png" alt="\">
例：一棵二叉树的先序遍历序列为ABCFHIDGJE，中序遍历序列为AHIFCJGDEB。
解题思路：
通过先序和中序或是中序和后序，都能唯一确定一颗二叉树。
每确定一个节点就把它从序列中暂时去除，这样就不会干扰下一步，帮助我们理清思路。
总结：
用一种自己理解的方式去做，就会发现其实不难。最近好几个人问过这个问题，总是做着做着就把自己绕进去了。其实这里只要知道三种遍历的规则，理清思路，就没问题啦！
这只是个人理解，有更好理解的欢迎交流学习！

Compare complex data structures using Java function comparison
Apr 19, 2024 pm 10:24 PM
When using complex data structures in Java, Comparator is used to provide a flexible comparison mechanism. Specific steps include: defining the comparator class, rewriting the compare method to define the comparison logic. Create a comparator instance. Use the Collections.sort method, passing in the collection and comparator instances.
Java how to loop through a folder and get all file names
Mar 29, 2024 pm 01:24 PM
Java is a popular programming language with powerful file handling capabilities. In Java, traversing a folder and getting all file names is a common operation, which can help us quickly locate and process files in a specific directory. This article will introduce how to implement a method of traversing a folder and getting all file names in Java, and provide specific code examples. 1. Use the recursive method to traverse the folder. We can use the recursive method to traverse the folder. The recursive method is a way of calling itself, which can effectively traverse the folder.
Java data structures and algorithms: in-depth explanation
May 08, 2024 pm 10:12 PM
Data structures and algorithms are the basis of Java development. This article deeply explores the key data structures (such as arrays, linked lists, trees, etc.) and algorithms (such as sorting, search, graph algorithms, etc.) in Java. These structures are illustrated through practical examples, including using arrays to store scores, linked lists to manage shopping lists, stacks to implement recursion, queues to synchronize threads, and trees and hash tables for fast search and authentication. Understanding these concepts allows you to write efficient and maintainable Java code.
PHP data structure: The balance of AVL trees, maintaining an efficient and orderly data structure
Jun 03, 2024 am 09:58 AM
AVL tree is a balanced binary search tree that ensures fast and efficient data operations. To achieve balance, it performs left- and right-turn operations, adjusting subtrees that violate balance. AVL trees utilize height balancing to ensure that the height of the tree is always small relative to the number of nodes, thereby achieving logarithmic time complexity (O(logn)) search operations and maintaining the efficiency of the data structure even on large data sets.
In-depth understanding of reference types in Go language
Feb 21, 2024 pm 11:36 PM
Reference types are a special data type in the Go language. Their values do not directly store the data itself, but the address of the stored data. In the Go language, reference types include slices, maps, channels, and pointers. A deep understanding of reference types is crucial to understanding the memory management and data transfer methods of the Go language. This article will combine specific code examples to introduce the characteristics and usage of reference types in Go language. 1. Slices Slices are one of the most commonly used reference types in the Go language.
Full analysis of Java collection framework: dissecting data structure and revealing the secret of efficient storage
Feb 23, 2024 am 10:49 AM
Overview of Java Collection Framework The Java collection framework is an important part of the Java programming language. It provides a series of container class libraries that can store and manage data. These container class libraries have different data structures to meet the data storage and processing needs in different scenarios. The advantage of the collection framework is that it provides a unified interface, allowing developers to operate different container class libraries in the same way, thereby reducing the difficulty of development. Data structures of the Java collection framework The Java collection framework contains a variety of data structures, each of which has its own unique characteristics and applicable scenarios. The following are several common Java collection framework data structures: 1. List: List is an ordered collection that allows elements to be repeated. Li

Mar 29, 2024 pm 12:42 PM
In-depth study of the mysteries of Go language data structure requires specific code examples. As a concise and efficient programming language, Go language also shows its unique charm in processing data structures. Data structure is a basic concept in computer science, which aims to organize and manage data so that it can be accessed and manipulated more efficiently. By in-depth learning the mysteries of Go language data structure, we can better understand how data is stored and operated, thereby improving programming efficiency and code quality. 1. Array Array is one of the simplest data structures
Hash table-based data structure optimizes PHP array intersection and union calculations
May 02, 2024 pm 12:06 PM
The hash table can be used to optimize PHP array intersection and union calculations, reducing the time complexity from O(n*m) to O(n+m). The specific steps are as follows: Use a hash table to map the elements of the first array to a Boolean value to quickly find whether the element in the second array exists and improve the efficiency of intersection calculation. Use a hash table to mark the elements of the first array as existing, and then add the elements of the second array one by one, ignoring existing elements to improve the efficiency of union calculations.
