Data structures are fundamental components in computer science that organize and store data in a way that allows efficient access and modification. They are essential for solving complex problems and optimizing performance in software development. Here's an overview of key data structures and their applications:
Common Data Structures
- Array: A collection of elements identified by index or key. 📊
- Linked List: A linear data structure where elements are stored in nodes connected by links. 🔗
- Stack: A LIFO (Last In, First Out) structure used for tasks like expression evaluation. ⬆️
- Queue: A FIFO (First In, First Out) structure for managing data in a sequential manner. ⬇️
- Tree: A hierarchical structure with nodes connected by edges, commonly used in databases and file systems. 🌳
- Graph: A non-linear structure representing relationships between nodes. 🧩
Applications of Data Structures
