Queue Data Structure Visualization: Step-by-Step Animated Guide in 40 Second

Queues are one of the fundamental data structures in computer science. They operate on the FIFO (First In, First Out) principle, where elements are added at the rear and removed from the front, similar to people standing in line. This article provides a step-by-step visualization of queues, helping you understand their structure, operations, and real-world applications.

What is a Queue?

A queue is a linear data structure that organizes elements sequentially. Unlike stacks, queues maintain the order in which elements are added.

• Enqueue: Adds an element to the end of the queue.
• Dequeue: Removes an element from the front of the queue.
• Front/Peek: Retrieves the element at the front without removing it.
• IsEmpty: Checks if the queue is empty.
• IsFull: Checks if the queue has reached its maximum capacity (for bounded queues).

Types of Queues
