What's your strategy for implementing a queue in software programming?

Question

Anonymous · Accepted Answer

A Queue Data Structure is a fundamental concept in computer science used for
storing and managing data in a specific order.

* It follows the principle of "First in, First out" (FIFO), where the first
   element added to the queue is the first one to be removed.

* It is used as a buffer in computer systems where we have speed mismatch
   between two devices that communicate with each other. For example, CPU and
   keyboard and two devices in a network

* Queue is also used in Operating System algorithms like CPU Scheduling and
   Memory Management, and many standard algorithms like Breadth First Search of
   Graph, Level Order Traversal of a Tree.

Queues can be implemented by using arrays or linked lists. Queues can be used to
implement job scheduling for an office printer, order processing for e-tickets,
or to create algorithms for breadth-first search in graphs.
