FAQs

Question: What are the main operations of a Stack?
Answer: The main operations of a Stack are Push (adding an element), Pop (removing the top element), and Peek (viewing the top element without removing it).

Question: How can I implement a Queue using Stacks?
Answer: A Queue can be implemented using two Stacks by using one Stack for enqueue operations and the other for dequeue operations, transferring elements as needed.
