Study Notes
Linked List and Node Structures
- A header node in a linked list serves as a starting point, simplifying operations like insertion and deletion by eliminating the need to check for an empty list.
- Doubly linked lists offer the advantage of bidirectional traversal, allowing navigation in both forward and backward directions compared to singly linked lists.
Trees and Their Structures
- In a binary search tree (BST), values less than the parent node are stored in the left subtree, ensuring efficient searching and sorting operations.
- The primary advantage of a B+ tree over a B tree is that B+ trees maintain all values in the leaf nodes, providing improved search efficiency and range queries.
Types of Trees
- A binary tree is a tree structure where each node has at most two children, while a binary search tree is a specialized form of a binary tree that maintains an ordered structure, enforcing that left child values are less than the parent and right child values are greater.
Abstract Data Types (ADT)
- The primary purpose of Abstract Data Types is to define a set of operations on data structures without exposing their implementation details, promoting abstraction and encapsulation in programming.
Queue Types and Applications
- Circular queues allow for reusing positions vacated after a dequeue operation, improving memory use efficiency.
- Stacks are commonly used for function call management, particularly in recursion, enabling backtracking through previous states.
Data Types
- Data types can generally be categorized into basic (primitive) types, like integers and characters, and user-defined types, which are structured types created by the user for specific applications.
User-Defined Data Types
- Defining operations for user-defined data types allows for encapsulation of functionality, promoting modular design and improving code readability and maintainability.
