A queue is a fundamental data structure in computer science that follows the First-In-First-Out (FIFO) principle. It is a linear data structure where elements are added at one end, called the rear or enqueue end, and removed from the other end, called the front or dequeue end.
Key Characteristics of a Queue:
FIFO Principle: The first element added to the queue is the first one to be removed. This is the core concept of a queue.
Enqueue and Dequeue Operations: Elements are added to the rear of the queue using the enqueue operation, and elements are removed from the front of the queue using the dequeue operation.
Limited Access: In a queue, you can only access the element at the front of the queue. You cannot randomly access elements in the middle of the queue.
Bounded or Unbounded: Queues can be bounded, mean...
