FAQs

Question: What are the main applications of stacks in programming?
Answer: Stacks are commonly used for function calls, expression evaluation, and backtracking algorithms.

Question: How do queues differ from stacks?
Answer: Queues operate on a first-in, first-out (FIFO) basis, while stacks follow a last-in, first-out (LIFO) principle.
