What are the differences between various queue types?

There are several types of queues, including simple queues, circular queues, priority queues, and dequeues. Would you like a brief overview of each?

Yes, please explain each type.

A simple queue follows FIFO (First In, First Out) order. A circular queue connects the end back to the front, allowing efficient use of space. A priority queue processes elements based on priority rather than order, and a dequeue allows insertion and deletion from both ends.

What are some use cases for each type?

Simple queues are used in scheduling tasks, circular queues in buffering, priority queues in algorithms like Dijkstra's, and deques in palindromic checks.

Which queue type is the most efficient?

Efficiency depends on the use case. For example, priority queues are efficient for tasks requiring prioritization, while simple queues are best for straightforward task management.
