Queues

A queue is a data structure that organizes items in a first-in, first-out (FIFO) order, similar to a line at a store. When a new item is added, it joins the end of the queue; items are removed from the front. Queues are used in various applications, such as managing print jobs, handling customer service requests, or processing tasks in computer systems. This structure ensures orderly processing, preventing conflicts by giving each item a fair chance to be handled in the order it arrived.
