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 using a linked list?
Answer: A Stack can be implemented using a linked list by creating nodes that point to the next node, allowing for dynamic memory allocation.
