What is a linear queue?

Can you explain what a linear queue is?

A linear queue is a data structure that follows a first-in, first-out (FIFO) order for processing elements.

How does it differ from a circular queue?

In a circular queue, the last position is connected back to the first position, allowing for efficient use of space.

What are some real-world applications of linear queues?

Linear queues are used in scenarios like scheduling tasks, managing requests in printers, and handling customer service calls.

Can you give me an example of how to implement a linear queue in Python?

Sure! You can use a list to implement a linear queue. Here's a simple example:

class LinearQueue:
    def __init__(self):
        self.queue = []

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

    def dequeue(self):
        if not self.is_empty():
            return self.queue.pop(0)

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