Queues

A queue is a fundamental data structure that operates on a first-in-first-out (FIFO) principle, meaning that the first element added to the queue will be the first one to be removed. This structure is analogous to a line of people waiting for service, where the person at the front is served first. Queues are widely used in various applications, such as managing tasks in operating systems, handling requests in web servers, and facilitating communication between processes. There are also variations like priority queues, where elements are served based on their priority rather than their order of arrival.
