  • Chapter 10 – Priority Queues

    Chapter 10 – Priority Queues

    Chapter 10: Priority Queues Welcome to Chapter 10! In this chapter, we’ll explore Priority Queues, a special type of queue where elements are processed based on their priority rather than the order in which they were added. Priority queues are incredibly useful in various real-world applications, such as task scheduling, Dijkstra’s shortest path algorithm, and…

  • Chapter 9 – Circular Queues

    Chapter 9 – Circular Queues

    Chapter 9: Circular Queues Welcome to Chapter 9! In this chapter, we’ll explore Circular Queues, which are an extension of the basic queue structure. Circular queues optimize memory usage by reusing spaces that are freed when elements are dequeued. This makes them highly useful for scenarios with fixed-size buffers, like operating systems and network packet…

  • Chapter 8 – Queues

    Chapter 8 – Queues

    Chapter 8: Queues Welcome to Chapter 8! In this chapter, we’ll explore Queues, another fundamental data structure that follows the First-In-First-Out (FIFO) principle. Queues are widely used in various computing scenarios like task scheduling, resource management, and buffering. What is a Queue? A Queue is a linear data structure where elements are inserted at the…

  • Chapter 7 – Stacks

    Chapter 7 – Stacks

    Chapter 7: Stacks Welcome to Chapter 7! In this chapter, we will delve deeply into the concept of Stacks, a fundamental data structure with a Last-In-First-Out (LIFO) ordering principle. Understanding stacks will equip you with a solid foundation for tackling a range of computational problems and algorithms. What is a Stack? A Stack is a…

  • Chapter 6 – Circular Linked Lists

    Chapter 6 – Circular Linked Lists

    Chapter 6: Circular Linked Lists Welcome to Chapter 6! In this chapter, we will explore Circular Linked Lists, a variation of linked lists where the last node in the list points back to the first node, forming a circular structure. This type of linked list is particularly useful in scenarios where you need a continuous…

  • Chapter 4 – Linked Lists

    Chapter 4 – Linked Lists

    Chapter 4: Linked Lists Welcome to Chapter 4! Now that you’ve become familiar with pointers and dynamic memory allocation, it’s time to explore how pointers unlock one of the most fundamental and powerful data structures: Linked Lists. If you’ve ever worked with arrays and found their fixed size to be limiting, you’re going to love…

  • Chapter 5 – Doubly Linked Lists

    Chapter 5 – Doubly Linked Lists

    Chapter 5: Doubly Linked Lists Welcome to Chapter 5! In this chapter, we’ll explore the Doubly Linked List—a more versatile type of linked list compared to the singly linked list. If you think of singly linked lists as one-way streets, doubly linked lists are like multi-lane roads with traffic flowing in both directions. This added…

  • Chapter 3: Pointers and Dynamic Memory Allocation

    Chapter 3: Pointers and Dynamic Memory Allocation

    Welcome to Chapter 3, where things start to get a little deeper and a lot more interesting—Pointers and Dynamic Memory Allocation. If arrays and strings were like lockers, pointers are like treasure maps that help you find where your valuables are stored in memory. Understanding pointers is critical for working with advanced data structures, so…

  • Chapter 3: Arrays and Their Operations

    Chapter 3: Arrays and Their Operations

    In the previous chapter, we briefly touched upon arrays. Now, let’s dig deeper into Arrays, one of the most basic yet powerful data structures. Arrays are widely used because they offer fast access and are easy to implement. In this chapter, we’ll explore arrays in more detail, discuss their operations, and see how they can…

  • Chapter 2: Understanding Data Structures

    Chapter 2: Understanding Data Structures

    In the previous chapter, we discussed what DSA is and got familiar with algorithmic notations like Big O, Little o, and others. Now, let’s dive into data structures — one of the core pillars of DSA. What Are Data Structures? A data structure is a way of organizing data in a computer so that it…
