What are some examples of queue implementations in programming?

There are several ways to implement queues in programming. Common examples include using arrays, linked lists, and built-in data structures like Python's collections.deque.

Can you explain how a queue works with a linked list?

Sure! In a linked list implementation, each element (node) contains data and a pointer to the next node. The front of the queue is where elements are removed, and the back is where elements are added.

What are the advantages of using a queue?

Queues are useful for managing tasks in a first-in, first-out (FIFO) manner, which is great for scheduling and handling asynchronous data.

Can you give me a code example of a queue using an array?

Certainly! Here's a simple example in Python:

class Queue:
    def __init__(self):
        self.items = []

    def enqueue(self, item):
        self.items.append(item)

    def dequeue(self):
        return self.items.pop(0) if not self.is_empty() else None

    def is_empty(self):
        return len(self.items) == 0
