This is a Python program to implement a queue using a linked list. The program creates a queue and allows the user to perform enqueue and dequeue operations on it. 1. Create a class Node with instance variables data and next. 2. Create a class Queue with …

Mar 25, 2025 · In this article, the Linked List implementation of the queue data structure is discussed and implemented. Print ‘-1’ if the queue is empty. Approach: To solve the problem follow the below idea: we maintain two pointers, front and rear. The front points to the first item of the queue and rear points to the last item.

Feb 11, 2025 · The queue can be efficiently implemented using a linked list. In this implementation, we dynamically allocate memory for each element in the queue using nodes, making it more flexible than using a fixed-size array. Key Operations in Queue: Enqueue: Add an element to the rear (end) of the queue.

Apr 14, 2021 · Learn how to implement a queue data structure using a linked list in Python with step-by-step examples and explanations.

Jul 16, 2021 · In this article, we will try to implement queue data structure with linked lists in python. A linked list is a linear data structure in which each data object points to one another.

Jan 5, 2023 · 1. enqueue() : Adds element to the back of Queue. 2. dequeue() : Removes and returns the first element from the queue. 3. first() : Returns the first element of the queue without removing it. 4. size() : returns the number of elements in the Queue. 5. isEmpty() : Return True if Queue is Empty else return False.

Dec 3, 2022 · Implementation of Queue using Linked List (Code) A queue can be implemented using an Array, Stack or Linked List but the easiest way is the array method. We are not concerned about the array implementation here, we will see the linked list representation.

Discover on how implementation of Queue linked list in Python. Queues are essential for managing data in a first-in, first-out (FIFO) manner. This Python implementation provides a solid foundation for understanding queues and their practical use in your programming projects.

Nov 21, 2024 · Queues are used in situations where tasks or data must be processed in the order they are received. You need to implement a queue data structure using a singly linked list using python. 1. Define the Node Class: The first step is to define a Node class that represents individual elements in the linked list. Each node contains two parts:

This lesson will teach us how to implement the queue using a singly linked list. We also know that two operations are possible on the queue, add and delete . See the image below to clearly understand how to implement add and delete operation on a queue using a linked list.
