Stacks are one of the most fundamental data structures in computer science. They follow a Last-In, First-Out (LIFO) strategy, ideal for tasks such as undo mechanisms, backtracking, and function calls. This exam evaluates your understanding of stacks, their operations, implementations, and practical applications in software development. 🧠📚
