Sample Questions

1multiple correct

Which of the following are real-life examples of stack?

Show answer

Pile of books, Stack of plates, Bangles on wrist

Pile of books, stack of plates, and bangles on wrist follow LIFO principle - you add/remove from the top. Queue at movie theater follows FIFO, and traffic signal is not a stack example.

2multiple choice

Which expression notation places operators between operands?

Show answer

Infix

Infix notation places operators between operands (like x + y). Prefix places operators before operands, and postfix places operators after operands.

3multiple choice

What is the postfix notation for the infix expression 'A + B'?

Show answer

A B +

In postfix notation, operators come after their operands. So 'A + B' becomes 'A B +' where both operands A and B are followed by the operator +.

4multiple correct

Which of the following are applications of stack in programming?

Show answer

Undo/Redo operations, Browser back button, Reversing a string

Stack is used in undo/redo operations, browser back button functionality, and string reversal because they all follow LIFO principle. Sorting and finding maximum don't typically use stack data structure.
