Study Notes
Overview of Stacks
- A stack is an Abstract Data Type (ADT) widely implemented across various programming languages.
- The name "stack" is derived from its resemblance to a physical stack, where items are added or removed in a specific order.
Characteristics of Stacks
- LIFO Principle: Stacks follow a Last In, First Out (LIFO) structure, meaning the last item added is the first to be removed.
- Basic Operations: Major operations associated with stacks include:
- Push: Adding an item to the top of the stack.
- Pop: Removing the item from the top of the stack.
- Peek/Top: Viewing the item at the top without removing it.
Applications of Stacks
- Commonly used for managing function calls in programming through call stacks.
- Facilitate undo mechanisms in software applications.
- Used in algorithm implementations such as depth-first search and expression evaluation.
Real-World Analogy
- Similar to stacking plates or books, where the last one placed on top is the first one that can be taken off, reinforcing the LIFO nature of stacks.
