Stacks

A stack is like a collection of objects arranged in a specific order, where the last item added is the first one to be removed—similar to a stack of plates. This is called "Last In, First Out" (LIFO). You add or remove items from the top of the stack only. Stacks are used in computer programming for managing tasks such as function calls, undo actions, and navigating data structures efficiently. They provide an organized way to handle temporary data, ensuring the most recent addition is accessed or removed first.
