Study Notes

Application of Arrays in Data Organization

Arrays allow for efficient storage and access of data elements by using contiguous memory locations.
They enable quick retrieval and manipulation of data due to their indexed structure, facilitating operations like sorting and searching.

Primitive Operations of a Stack Data Structure

Push: Adds an element to the top of the stack.
Pop: Removes the top element from the stack.
Peek/Top: Returns the top element without removing it.
IsEmpty: Checks if the stack has no elements.

Two Implementations of a Linked List

Singly Linked List: Consists of nodes with data and a pointer to the next node, allowing traversal in one direction.
Doubly Linked List: Contains nodes with pointers to both the next and previous nodes, enabling bidirectional traversal.

Operations on a Linked List

Insertion: Adding a new node at the beginning, end, or a specific position.
Deletion: Removing a node from the beginning, end, or a specific position.
Traversing: Visiting each node to access or display data.
Searching: Finding a node with a particular value.

Application of a Queue Data Structure

Queues are used in scenarios requiring first-in, first-out (FIFO) processing, such as scheduling tasks, managing print jobs, or handling requests in server systems.

Types of Linked Lists

Singly Linked List: Single direction traversal.
Doubly Linked List: Bidirectional traversal.
Circular Linked List: Last node points back to the first node, creating a circular structure.

Basic Operations for AVL Tree, B Tree & Binary Heaps

AVL Tree: Insert, delete, rotate (to maintain balance), and search operations.
B Tree: Insert, delete, split nodes, and search operations; suitable for disk storage.
Binary Heap: Insert, delete (typically involves removing the root), and find-min/find-max operations, efficient for priority queue implementation.

Relationship between Data Structure and Algorithm in Computer Science

Data structures provide the necessary format for organizing and storing data, while algorithms are procedures for manipulating that data.
The efficiency of algorithms often depends on the choice of data structure, impacting performance and resource usage.

Main Objective of Studying Data Structures and Algorithms

To develop efficient solutions for computational problems, improving performance and reducing resource consumption in software applications.

Definition of 'Data Structure'

A data structure is a specialized format for organizing, processing, and storing data, allowing efficient access and modification.

Four Main Specifications of a Data Structure

Type of data elements it holds.
The relationships among the data elements.
Operations that can be performed on the data elements.
The performance characteristics of these operations.

Effect of Data Structure on a Program

The choice of data structure can significantly influence the performance, scalability, and efficiency of program execution.
A well-chosen data structure optimizes resource usage, enhancing speed and reducing memory consumption.

Basic Terminology Used with Trees

Node: Fundamental part of the tree that contains data.
Root: The top node of the tree.
Leaf: A node that does not have any children.
Height: The length of the longest path from the root to a leaf.

Two Data Structure Representations for Binary Trees

Array Representation: Uses a contiguous block of memory, indexing children through calculated indices.
Pointer Representation: Uses nodes with left and right pointers to represent child relationships.

Techniques Used for Graph Representations

Adjacency Matrix: A 2D array indicating the presence of edges between nodes.
Adjacency List: A collection of lists where each list corresponds to a graph vertex and stores its adjacent vertices.

Two Graph Traversal Algorithms

Depth-First Search (DFS): Explores as far along a branch as possible before backtracking.
Breadth-First Search (BFS): Explores neighbors of a node before moving on to their neighbors, ensuring the shortest path is found in unweighted graphs.
