Queue Data Structure - Enqueue and Dequeue through Animation

A linear queue is a linear data structure that follows the First In First Out (FIFO) principle. The element inserted first is the one that gets removed first. It is called linear because the elements are arranged in a sequential manner.
Front: Points to the first element of the queue.
Rear: Points to the last element of the queue.
Enqueue: Add an element at the rear end.
Dequeue: Remove an element from the front end.
Advantage - Easy to implement.
Disadvantage - You cannot enqueue new elements once the rear reaches the end of the array, even though there may be free space at the front.
