Data Structures - 1

Data Structures are essential for organizing and managing data efficiently, enabling quick access and modification. They are crucial for designing efficient algorithms and are widely used in software engineering, databases, AI, and more. Key Data Structures: 1. Arrays: Fixed-size, efficient for indexing. 2. Linked Lists: Dynamic size, good for insertions/deletions. 3. Stacks: LIFO structure, used in undo functionality. 4. Queues: FIFO structure, used in job scheduling. 5. Trees: Hierarchical, used in file systems. 6. Graphs: Represent relationships, used in social networks. 7. Hash Tables: Fast lookups, used in dictionaries
