Can you explain how a queue works in programming?
Sure! A queue is a data structure that follows the First In First Out (FIFO) principle, meaning the first element added is the first one to be removed.
What are some real-life examples of queues?
Common examples include lines at a grocery store, waiting for a bus, or print jobs in a printer queue.
How do queues differ from stacks?
Queues operate on FIFO, while stacks use Last In First Out (LIFO), meaning the last element added is the first to be removed.
Can you show me a simple code example of a queue?
Certainly! Here's a simple implementation in Python:
from collections import deque
queue = deque()
queue.append('first') # Add to the queue
queue.append('second')
print(queue.popleft()) # Removes 'first'
