Study Notes
Time Complexity of Data Structures
- Hash tables offer average O(1) time complexity for search, insertion, and deletion.
- Binary search trees provide O(log n) time complexity for these operations.
Memory Utilization
- Efficient memory management reduces waste; data structures like linked lists use dynamic allocation.
- Arrays require predefined memory allocation, leading to potential inefficiencies.
Data Integrity and Manipulation
- Structured organization ensures data integrity and consistency.
- Stacks follow Last In, First Out (LIFO) principle, suitable for undo operations.
Complex Problem Solving
- Many algorithms rely on specific data structures for effectiveness, like Dijkstra’s algorithm using priority queues.
Reusability and Abstraction
- Data structures promote modular and reusable code.
- Abstract Data Types (ADTs) like lists and queues abstract implementation details.
Scalability
- Efficient data structures are vital for handling large datasets, exemplified by B-trees in databases.
Improved Performance in Applications
- Real-time systems and applications such as operating systems and database management require efficient data structures.
- Routing tables in networking and process scheduling in operating systems are key examples.
Search and Retrieval
- Fast search and retrieval are facilitated by data structures; binary search trees enable efficient operations.
Data Relationships
- Tree structures represent hierarchical data, while graphs represent networks and relationships.
Concurrency Control
- Multi-threading requires efficient data structures to maintain data integrity and consistency.
- Concurrent data structures like queues and stacks are essential in concurrent programming.
Optimization
- Algorithms maximize or minimize criteria; for instance, linear programming optimizes resource allocation.
Writing an Algorithm
- Understand the problem clearly, defining inputs, outputs, and constraints.
- Create a high-level outline, focusing on clarity, modularity, efficiency, maintainability, and correctness.
Algorithm Complexity
- Time complexity analyzes how the execution time of an algorithm grows with input size.
- Common notations include best case, average case, and worst case scenarios.
Dynamic vs Static Data Structures
- Static structures, like arrays, have fixed sizes, while dynamic structures, such as linked lists, can change size at runtime.
Homogeneous vs Heterogeneous Data Structures
- Homogeneous structures consist of the same data type (e.g., arrays), while heterogeneous ones contain different types (e.g., structures in C).
Hash-based Data Structures
- Hash tables use hash functions for fast key-value pair retrieval, achieving average O(1) time complexity.
Indexed and Composite Data Structures
- Indexed structures (e.g., arrays) allow direct access via indices, while composite structures combine multiple data types (e.g., classes).
File Structures
- Organizes data in storage; examples include sequential, indexed, and hashed file organization.
Choosing the Right Data Structure
- Selection depends on data nature, required operations, efficiency needs, and memory usage considerations.
