Fundamentals of Stack and Queue Data StructuresStack Data StructureConceptA stack is a specialized linear data structure that permits insertion and deletion operations only at one fixed end, known as the top. The opposite end is called the bottom. Elements in a stack follow the Last-In-First-Out (LIFO) principle. The insertion operation is call ...

A stack is a linear collection that restricts element access to a single endpoint, commonly referred to as the top. This constraint enforces a Last-In-First-Out (LIFO) ordering, meaning the most recently added item is always the first to be removed. The two fundamental operations are push (insertion at the top) and pop (removal from the top). A ...
