What are the differences between queue implementations?

There are several types of queue implementations, such as linked lists, arrays, and circular buffers. Each has its own advantages and disadvantages.

Can you explain the advantages of using a linked list for queues?

Sure! Linked lists allow dynamic memory allocation, which means they can grow and shrink as needed without a fixed size, making them flexible.

What about array-based queues? What are their pros and cons?

Array-based queues are generally faster for accessing elements due to contiguous memory allocation, but they have a fixed size and can lead to wasted space if not fully utilized.

How does a circular buffer work in queue implementation?

A circular buffer uses a fixed-size array but treats it as circular, allowing efficient use of space and avoiding the need for shifting elements when enqueuing or dequeuing.
