Study Notes
Stack Operations
- The two main operations of a stack are push and pop.
Stack Characteristics
- LIFO stands for Last-In-First-Out in the context of a stack.
- A stack is considered a Last-In-First-Out (LIFO) data structure.
Peek Operation
- The peek operation retrieves the value of the last element added to the stack without modifying the stack.
Data Structure Classification
- A stack is a type of Linear Data Structure.
Stack Analogy
- The term 'stack' in computer science is analogous to a stack of plates, where elements are added and removed from the top.
Element Ordering
- The term used to describe the order in which an element is added to or removed from a stack is Last-In-First-Out (LIFO).
Push and Pop Operations
- The push and pop operations occur at the top of the stack.
Stack Illustration
- The analogy of a 'stack of plates' illustrates that elements are added and removed from the top of the stack, following the Last-In-First-Out (LIFO) principle.
