Welcome to visit！
1.基本概念：
數據結構是組織和存儲數據的方式，是計算機科學的基礎之一。數據結構包括兩個方面的內容：數據的邏輯結構（邏輯關系）和數據的存儲結構（物理存儲方式）。數據的邏輯結構包括線性結構（如數組、鏈表）、樹形結構（如二叉樹、B樹）、圖形結構等。數據的存儲結構包括順序存儲結構和鏈式存儲結構等不同的存儲方式。
1.Basic concepts:
Data structure is a way of organizing and storing data, and is one of the foundations of computer science. The data structure includes two aspects: the logical structure of data (logical relationships) and the storage structure of data (physical storage methods). The logical structure of data includes linear structures (such as arrays, linked lists), tree structures (such as binary trees, B-trees), graphical structures, etc. The storage structure of data includes different storage methods such as sequential storage structure and chain storage structure.
2.常見數據結構：
- 數組（Array）：一種線性結構，由相同數據類型的元素組成，存儲在連續的內存空間中。
- 鏈表（Linked List）：一種線性結構，由節點組成，每個節點包含數據和指向下一個節點的指針。
- 棧（Stack）：一種特殊的線性結構，具有「先進後出」的特點。
- 隊列（Queue）：一種特殊的線性結構，具有「先進先出」的特點。
- 樹（Tree）：一種非線性結構，由節點和邊組成，具有層次關系。
- 圖（Graph）：一種非線性結構，由頂點和邊組成，用於表示各種關系。
- 堆（Heap）：一種特殊的樹形結構，通常用於實現優先隊列等數據結構。
2. Common data structures:
- Array: A linear structure composed of elements of the same data type, stored in a continuous memory space.
- Linked List: A linear structure consisting of nodes, each containing data and a pointer to the next node.
- Stack: A special linear structure with the characteristic of "first in, last out".
- Queue: A special linear structure with the characteristic of "first in, first out".
- Tree: A non-linear structure composed of nodes and edges, with hierarchical relationships.
- Graph: A non-linear structure composed of vertices and edges, used to represent various relationships.
- Heap: A special tree structure commonly used to implement data structures such as priority queues.
3.操作與算法：
不同的數據結構支持不同的操作，如插入、刪除、查找、遍歷等。對於每種數據結構，都有相應的操作和算法，如數組的查找算法、鏈表的插入算法、樹的遍歷算法等。算法的效率與數據結構的選擇密切相關，常用的性能分析方法包括時間復雜度和空間復雜度。
3. Operations and algorithms:
Different data structures support different operations, such as insertion, deletion, search, traversal, etc. For each data structure, there are corresponding operations and algorithms, such as array search algorithms, linked list insertion algorithms, tree traversal algorithms, etc. The efficiency of algorithms is closely related to the selection of data structures, and commonly used performance analysis methods include time complexity and spatial complexity.
4.應用場景：
不同的數據結構適用於不同的場景和問題，選擇合適的數據結構可以提高程序的性能和效率。例如，數組適用於隨機訪問和固定大小的數據集合，鏈表適用於頻繁的插入和刪除操作，樹適用於層次關系較為復雜的數據，哈希表適用於快速查找和更新數據等場景。數據結構的應用涵蓋了各個領域，包括算法設計、數據庫系統、網絡通信、操作系統等。
4. Application scenarios:
Different data structures are suitable for different scenarios and problems, and selecting the appropriate data structure can improve the performance and efficiency of the program. For example, arrays are suitable for random access and fixed size datasets, linked lists are suitable for frequent insertion and deletion operations, trees are suitable for data with complex hierarchical relationships, and hash tables are suitable for fast data lookup and update scenarios. The application of data structures covers various fields, including algorithm design, database systems, network communication, operating systems, etc.
