Stack Visualizer

Null

Size of the Stack:-

Peek value(Top) :-

Stack is Empty:-

A stack is a linear data structure that follows the LIFO (Last In, First Out) principle.

The last element added is the first one removed — like a stack of plates.

Types of Stack Implementations:-

  1. Array-based Stack: Fixed size, fast access.
  2. Linked List Stack: Dynamic size, flexible.
  3. Call Stack (System): Used internally in function calls.

Core Operations:-

  1. push(x): Add x to top of the stack
  2. pop(): Remove and return top element
  3. peek(): Return the top element
  4. is Empty(): Return true if stack is empty

Time Complexity:- O(1)

Space Complexity:- O(n)
