What logic do queues follow?

Queues operate on a principle known as First-in, First-out (FIFO). This means that the first element added to the queue will be the first one to be removed. This can be likened to a line of people waiting for service: the person at the front of the line is the first to be served, and as new people join the line, they are added to the back.

In practical terms, when you enqueue (add) an element, it goes to the back of the queue, and when you dequeue (remove) an element, you take the one that has been in the queue the longest, which is at the front. This behavior is essential for many applications, such as task scheduling and resource management, where maintaining the order of processes or requests is crucial.

The other concepts mentioned, such as Last-in, first-out (used by stacks) and Random access (which refers to data structures that allow access to elements at arbitrary positions), do not accurately describe how queues function. Thus, recognizing that queues adhere to the FIFO principle is fundamental to understanding their behavior and usage in programming and data management.
