FAQs
Question: What are the primary operations of a stack? Answer: The primary 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 is a queue different from a stack? Answer: A queue follows the FIFO (First In First Out) principle, while a stack follows the LIFO (Last In First Out) principle.

Q. How can stacks be used to check for balanced parentheses in an expression?
A.
By counting the number of parentheses
B.
By using a queue to store parentheses
C.
By pushing opening parentheses onto the stack and popping for closing ones
D.
By sorting the parentheses
Solution
Stacks can be used to check for balanced parentheses by pushing opening ones and popping when a closing one is encountered.
Correct Answer:
C
— By pushing opening parentheses onto the stack and popping for closing ones
