In a messaging application, how would you implement message delivery using a queue to ensure messages are delivered in the order they were sent?

Implementing a FIFO (First-In-First-Out) approach using a queue is ideal for ensuring messages are delivered in the order they were sent. In this approach, messages are added to the end of the queue and processed in the same order they were received, maintaining chronological order. A LIFO (Last-In-First-Out) approach would reverse the message order, which is not suitable for messaging applications. Priority-based approaches may prioritize certain messages over others, potentially disrupting the order of delivery. Circular buffers are more suited for fixed-size data storage, not for maintaining message order in a dynamic messaging system.
