Chapter Introduction
Who This Chapter is For
This chapter is recommended for readers who wish to systematically master data structures and algorithms.
For readers looking to quickly improve their problem-solving skills for written exams, a complete study of this chapter is not necessary. Please refer to the Cramming Guide.
Chapter Overview
The best way to learn something is to implement it yourself. This chapter will not cover algorithmic problems but will guide readers through understanding and implementing all common data structures.
By grasping the underlying principles of these data structures, you will be able to accurately leverage their characteristics and understand the time complexity of your code when solving algorithmic problems in subsequent chapters.
Tip
The focus of this chapter is to help readers understand the implementation principles, advantages, disadvantages, and limitations of each data structure. The provided Java/C++/Golang/Python/JavaScript code implementations ensure correctness and readability.
Advanced optimizations and best practices at the programming language level are beyond the scope of this site's teachings. For a deeper understanding, you can refer to the standard libraries of the respective programming languages.
Of course, the multi-language code I provide may contain minor errors. Your feedback and corrections are welcome to help us progress together!
Throughout this chapter, the Algorithm Visualization Panel will frequently be used to visualize slightly complex data structure operations. The visualization code is written in JavaScript, but it is straightforward, making it easy to understand regardless of your familiarity with JavaScript.
