Category: Queues

A queue is a data structure that follows the First-In-First-Out (FIFO) principle, meaning the element that is added first to the queue is the first one to be removed. In...

Circular queues are a typical data structure in operating systems. It is employed to control how computer programs or procedures are carried out. To hold the processes in the order...

In this blog, we will learn about queue in data structure we will learn all about the queue, and operations can perform on queue. Followed by types of queue in...

A priority queue is a type of queue data structure where each element is assigned a priority and elements with higher priority are served before elements with lower priority. It...

Queues are essential in data structures for orderly data processing. Queue implementation becomes a powerful technique for organizing and controlling data flow when arrays are used as the foundation. This...

In this post, we'll talk about what a queue is and how it works. The queue is one of the most used data structures. The most helpful data structure in...

In this article, we will learn what is the queue, the algorithm to implement queue using linked list, the algorithm of the queue with an example dry-run, the program to...

In this article, we will be discussing Data Structures in C++ topics i.e. Queue and heap. A data structure is not only used for organizing the data. It is also...

Embarking on the journey of understanding Prim's algorithm and its implementation using the priority_queue in the C++ Standard Template Library (STL) opens a gateway to the realm of efficient minimum...

What is Deque? Deque is a double ended queue, i.e. a special kind of queue in which insertion and deletion can be done at the both rear as well as...

Queues are a fundamental data structure used in computer science to manage and store data. They are used in various applications, from operating systems to networking systems, and are widely...

What is the queue? A queue is basically a linear data structure that works on the principle of FIFO (First in First out) which means an element that is enqueued(Insert)...

What is the priority queue? Priority queues are abstract data structures where each element in the queue has a priority value. For example, in any airline, baggage under the “First-Class”...

Circular Queue It is a linear data structure that works on the principle of FIFO (First in First out). In this type of queue element can be added in any...

Problem Statement: Given a queue, we have to sort the queue using a recursive function without using any loop. We can only use the standard functions for it:- enqueue(element): Add...

In this article, we'll look at how to reverse a queue. We must reverse a queue with only standard operations: enqueue(element): Add an element to the queue's tail. dequeue(): Removes...

Reverse the first k elements in the queue is a common problem in data structures and algorithms. A queue is a data structure that follows the FIFO (First In First...

Problem Statement: Given a queue, we have to make a recursive function to reverse it. Queue: A Queue is a linear data structure. Queue follows the FIFO rule i.e. First...

What is a Queue? Queue follows the principle of FIFO (First in First out) i.e. element which is inserted first will be removed first. The operation for insertion of elements...

Sorting a queue without utilizing extra space presents an intriguing challenge in computer science. Queues, a fundamental data structure, follow the FIFO (First-In-First-Out) principle, making their sorting a complex task...

What is Multilevel Queue Scheduling? In multilevel queue scheduling, all the processes are assigned permanently to the queue at the time of entry. Processes will not move between queues and...

Priority queues are specialized data structures that manage a set of elements each with an associated priority. Unlike regular queues, where elements are dequeued in the order they were enqueued...

Firstly, we’ll see what the queue is. Queue A queue is basically a linear data structure that works on the principle of FIFO (First in First out) which means an...

Queue: The queue is a linear data structure that works on the principle of First in First out (FIFO). In the queue, the element which is added at least recently...

Queue A queue is basically a linear data structure that works on the principle of FIFO (First in First out) which means an element that is enqueued first will be...

Priority queues are fundamental data structures that play a crucial role in various computer science applications, from operating systems to graph algorithms and event-driven simulations. They provide efficient access to...

A multilevel queue scheduling algorithm divides the ready queue into multiple levels or tiers, each with a different priority. The appropriate level is then assigned to the processes based on...

The circular queue has several advantages over linear queue. It uses memory more efficiently because it can reuse the space that becomes available when elements are dequeued. The circular queue...
