Circular Queue is a type of queue in which the last element is connected to the first element to make a circular data structure. In other words, a circular queue wraps around and reuses the space that the first element took up after the last element. This type of queue is useful when w...
A queue is a type of data structure that operates according to the ‘First-In-First-Out’ (FIFO) principle, which states that the first item entered into the queue will also be the first one taken out. This is comparable to a line in real life, where those in front of the line are...
A queue is an object (an abstract data structure - ADT) that allows the following operations: Enqueue: Add an element to the end of the queue Dequeue: Remove an element from the front of the queue IsEmpty: Check if the queue is empty IsFull: Check if the queue is full Peek: Get th...

The elements of the queue are enumerated, which does not change the state of the queue. The Dequeue method is used to dequeue the first string. The Peek method is used to look at the next item in the queue, and then the Dequeue method is used to dequeue it....
In the circular queue, when the queue is full, and when we remove elements from the front since last and first positions are connected, we can insert the elements at the rear which was vacated by deleting the element. In the next section, we will learn about the basic operations of the...
