Queues
Queue A Queue is a special linear data structure that only allows insertion at one end of the structure and deletion at the other end. The end where insertion occurs is called the Rear, and the end where deletion occurs is called the Front. Queue operations follow the First-In, First-Out (FIFO) principle. Enqueue Add a new element at the rear of the queue. Dequeue Remove and return the element at the front of the queue.
