The Data Structures Basics

In computer science, a data structure is a way of organising and storing data for efficient access and modification. Data structures can be thought of as the building blocks of software, providing a means to organise and manage data in a systematic and optimised manner.

Data structures can be categorised into two main types: linear data structures and non-linear data structures. Linear data structures include arrays, linked lists, stacks, and queues, where elements are organised in a linear fashion. Non-linear data structures, on the other hand, include trees, graphs, and hash tables, allowing for more complex relationships between data elements.

Benefits of Data Structures

Data structures offer a myriad of advantages, ranging from improved performance and memory management to enhanced data organisation and integrity. In this article, we will explore the benefits of data structures, dissecting how data structures enable better algorithms, streamlined memory utilisation, modular code design, and data security. Data structures offer several benefits that are crucial for efficient programming:

• Efficiency: Data structures are designed to optimise data access, insertion, and deletion operations, leading to faster algorithms and programs.

• Memory Management: They help in efficient memory utilisation, reducing wastage and improving performance.

• Organisation: Data structures provide a systematic way to organise data, making it easier to manage and maintain.

• Modularity: They promote code modularity and encapsulation, thereby enhancing code readability and maintainability.

• Data Integrity: Well-designed data structures can enforce data integrity and security, preventing unauthorised access or modification.

Now that we have a grasp of the basics, let us explore some common examples of data structures.

Examples of Data Structures

Examples of data structure basics are the building blocks of data organisation, enabling the efficient storage, retrieval, and manipulation of information. In this section, we will explore a spectrum of data structures, from the elementary arrays and linked lists to the detailed hierarchies of trees and the networked complexities of graphs.

• Arrays: A fundamental data structure that stores a collection of elements in contiguous memory locations.

• Linked Lists: Consist of nodes connected by pointers, allowing for dynamic data storage.

Stacks: A Last-In-First-Out (LIFO) linear data structure used for managing function calls and undo operations. Here is a java code illustration :

import java.util.Stack;

public class BalancedParentheses {

public static boolean isBalanced(String parentheses) {

Stack<Character> stack = new Stack<>();

for (char bracket : parentheses.toCharArray()) {

if (bracket == '(' || bracket == '[' || bracket == '{') {

stack.push(bracket);

} else if (bracket == ')' && !stack.isEmpty() && stack.peek() == '(') {

stack.pop();

} else if (bracket == ']' && !stack.isEmpty() && stack.peek() == '[') {

stack.pop();

} else if (bracket == '}' && !stack.isEmpty() && stack.peek() == '{') {

stack.pop();

} else {

return false; // Unmatched closing bracket or mismatched types

}

}

return stack.isEmpty(); // Stack should be empty for a balanced expression

}

public static void main(String[] args) {

String balancedString = "{[()]}";

String unbalancedString = "{[(])}";

System.out.println("Is \"" + balancedString + "\" balanced? " + isBalanced(balancedString));

System.out.println("Is \"" + unbalancedString + "\" balanced? " + isBalanced(unbalancedString));

}

}

• Queues: A First-In-First-Out (FIFO) linear data structure often used for task scheduling and managing resources.

• Trees: Hierarchical structures with nodes connected by edges. Examples include binary trees, AVL trees, and red-black trees.

• Graphs: A collection of nodes and edges used to represent complex relationships and networks.

• Hash Tables: Efficient data structures for storing key-value pairs, enabling fast data retrieval.

• Heaps: Specialised trees used for priority queue operations, such as min and max heap.
