Study Notes
Data Structure Overview
- Data structures store and organize data efficiently for use in algorithms.
- Classified into two main categories: Linear and Non-Linear.
Linear Data Structure
- Elements are stored sequentially, with connections to the previous and next elements.
- Traversal and access of elements occur in a single run.
- Easier implementation due to sequential organization in memory.
- Single element access at a time, with types including:
- Array: Fixed-size collection of elements.
- Queue: FIFO (First In First Out) structure for managing data.
- Stack: LIFO (Last In First Out) structure for data management.
- Linked List: A series of nodes where each node points to the next.
Non-Linear Data Structure
- Elements are arranged non-sequentially and cannot be traversed in a single run.
- Each element can connect to more than two other elements.
- Types include:
-
Trees: Hierarchical structure with parent-child relationships.
- Example: Organizational chart - a manager (parent) linked to officers and clerks (children).
-
Graphs: Comprised of vertices and edges.
- Used to connect data elements (vertices) through relationships (edges).
- Applicable in real-world scenarios like networks (telephone, circuit, social platforms).
-
Trees: Hierarchical structure with parent-child relationships.
Comparison: Linear vs Non-Linear
- Linear structures have sequential connections; non-linear structures have multiple connections.
- Linear structures allow single traversal; non-linear structures require multi-directional access.
