FAQs

Question: What is the main 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 do I analyze the complexity of stack operations?
Answer: The complexity of basic stack operations like push and pop is O(1), meaning they can be performed in constant time.
