What is a Stack in Data Structure?
Why do we use Stack in DSA and where is it applied in real life?

Welcome to The Techzeen, where DSA concepts are explained in Hindi/Urdu with clarity, diagrams, and real-world use cases.

In this video, I’ll cover:
What is Stack? (Definition + LIFO Principle)
Why we use Stack in Data Structures?
Real-life Examples of Stack:
* Undo / Redo (Text Editors)
* Browser Back / Forward
* Function Calls (Call Stack in Recursion)
* Compiler Expression Evaluation
* Balanced Parentheses, Syntax Highlighting
* Backtracking (Maze, Chess, Games)
* String Reversal & Memory Management

Why Stack is not stored separately but implemented using Array or Linked List
Difference between Array-based & Linked List-based Stack
Stack Operations: Push, Pop, Peek explained theoretically

This tutorial is perfect for:
* Beginners starting DSA in 2025
* Students preparing for Coding Interviews.
* Anyone who wants strong fundamentals in Stack Data Structure.
