Queues

Queues are fundamental data structures that operate on a first-in-first-out (FIFO) principle, meaning the first element added to the queue is the first one to be removed. They are widely used in various applications, such as managing tasks in operating systems, handling requests in web servers, and organizing data in simulations. Queues can be implemented using arrays or linked lists and can also be categorized into different types, such as simple queues and priority queues, where elements are served based on their priority rather than their order of arrival. Understanding queues is essential for efficient algorithm design and data management.
