What are some common queue algorithms implemented in different programming languages?

Can you explain some common queue algorithms and how they are implemented in different programming languages?

Sure! Common queue algorithms include FIFO (First In, First Out), LIFO (Last In, First Out), and priority queues. In Python, you can use the queue module for FIFO queues. In Java, the LinkedList class can be used to implement a queue. Would you like examples in specific languages?

Yes, can you show me how to implement a FIFO queue in Python and Java?

Absolutely! In Python, you can implement a FIFO queue like this:

import queue

fifo_queue = queue.Queue()
fifo_queue.put(1)
fifo_queue.put(2)
print(fifo_queue.get())  # Outputs: 1

In Java, it looks like this:

import java.util.LinkedList;
import java.util.Queue;

Queue<Integer> fifoQueue = new LinkedList<>();
fifoQueue.add(1);
fifoQueue.add(2);
System.out.println(fifoQueue.poll());  // Outputs: 1

What about priority queues? How are they different?

Priority queues differ from regular queues in that they serve elements based on priority rather than the order they were added. In Python, you can use the heapq module to implement a priority queue. In Java, the PriorityQueue class serves this purpose. Would you like to see examples for priority queues as well?
