queue

Queues are a fundamental data structure that many developers encounter in their careers. Think of a queue as a line of people waiting for coffee; the first person in line is the first one to be served. This First-In-First-Out (FIFO) principle is crucial for various applications, from scheduling tasks in operating systems to managing print jobs.
