Question: Which application uses both stacks and queues?
Options:
Depth-first search
Breadth-first search
Expression evaluation
Memory allocation
Correct Answer: Expression evaluation
Solution:
Expression evaluation often uses stacks for operators and operands, while queues can be used for managing the order of operations.

Questions & Step-by-Step Solutions
Which application uses both stacks and queues?
Step 1: Understand what a stack is. A stack is a data structure that follows the Last In First Out (LIFO) principle, meaning the last item added is the first one to be removed.
Step 2: Understand what a queue is. A queue is a data structure that follows the First In First Out (FIFO) principle, meaning the first item added is the first one to be removed.
Step 3: Learn about expression evaluation. This is the process of calculating the value of an expression, like a mathematical equation.
Step 4: Realize that when evaluating expressions, stacks are used to hold operators (like +, -, *, /) and operands (the numbers).
Step 5: Understand that queues can be used to manage the order in which operations are performed, especially in more complex expressions.
Step 6: Conclude that both stacks and queues are important in expression evaluation to handle different parts of the process.
