Abstract：Queue Data Structure is a linear data structure organized on the First-In-First-Out (FIFO) principle. It models real-world queuing behavior, where data elements are added at one end (called the rear) and removed from the other end (called the front) in the same order they were inserted.

Introduction

Queue Data Structure is a linear data structure organized on the First-In-First-Out (FIFO) principle. It models real-world queuing behavior, where data elements are added at one end (called the rear) and removed from the other end (called the front) in the same order they were inserted. This design ensures fairness and sequential processing, making it widely applicable in scenarios requiring ordered execution or asynchronous coordination, such as task scheduling in operating systems, communication buffering in message middleware, network request queuing, and print job management.

Applicable Scene

The queue structure is suitable for all system scenarios that require guaranteed task processing order and fairness, such as process scheduling in operating systems, printer job queuing, network request buffering, asynchronous communication in message middleware, and request traffic peak shaving and valley filling in high-concurrency systems.

Pros: Naturally ensures fairness and predictability in processing order through the First-In-First-Out (FIFO) mechanism.

Cons: Does not allow direct access to or manipulation of non-front elements, and can lead to memory accumulation in scenarios with high production but low consumption rates.
