stack 🔊
Meaning of stack
A stack is an orderly pile of objects, typically arranged one on top of another. In computing, it refers to a data structure that follows the Last-In-First-Out (LIFO) principle.
Key Difference
Unlike a heap or a queue, a stack strictly follows the LIFO principle, meaning the last item added is the first one removed.
Example of stack

- The program uses a stack to manage function calls efficiently.
