What is the difference between a stack and a queue in data structures?
Hey Mark
In the realm of data structures, both stacks and queues serve as linear collections for storing elements, but they differ significantly in their operational mechanics. A stack adheres to the Last-In-First-Out (LIFO) principle, where the most recent item added, or “pushed”, is the first to be removed or “popped”. Conversely, a queue follows the First-In-First-Out (FIFO) principle, ensuring that the earliest item entered is the first to exit or be “dequeued”.
