FAQs

Question: What is the difference between a stack and a queue?
Answer: A stack follows the Last In First Out (LIFO) principle, while a queue follows the First In First Out (FIFO) principle.

Question: How can I implement a stack in Python?
Answer: A stack can be implemented using a list where you can use the append() method to push and the pop() method to remove elements.
