Master Stack Patterns | DSA for Interviews

Описание: Stacks are not about memorizing push and pop operations.
Stacks are about understanding patterns.

In this video, I explain the Stack Data Structure in a pattern-based way, exactly how stack problems appear in coding interviews and real problem-solving scenarios.

Instead of solving random questions, we focus on:
1- how stack problems are framed
2- how to identify the correct stack pattern
3- why stack naturally fits certain problems

Patterns covered in this video:
1- Basic stack operations (push, pop, peek)
2- Next greater / next smaller element pattern
3- Monotonic stack pattern
4- Stack for expression evaluation
5- Stack for recursion simulation
6- Stack in string and array problems


Each pattern is explained with:
clear intuition
problem structure
common interview examples

Who this video is for:
beginners who struggle with stack problems
students preparing for coding interviews
anyone who wants to think logically instead of memorizing code


Interview insight:
If a problem involves:
reversing order
last seen element
nearest greater or smaller element
matching brackets
Stack should immediately come to mind.

Practice pattern-wise:
I’ve shared my DSA sheet where stack questions are grouped pattern-wise, not randomly.
