Find the Details below: Video Name: What are Monotonic Data Structures | Monotonic Stack | Template | codestorywithMIK Video #: 2 🔍 Mastering DSA Smartly: Powerful Patterns, Simplified. 🎥 Welcome to the 2nd video of my Monotonic Data Structures Playlist! 🚀 In this session, we’ll build a solid understanding of Monotonic Stacks, their structure, intuition, and most importantly — a universal template you can apply in many classic DSA problems. 🔍 What’s Inside? In this video, we decode the core idea behind Monotonic Data Structures and understand how to use them to solve problems like Next Smaller Element, Next Greater Element, and more — in O(n) time! We’ll cover: ✅ What are Monotonic Data Structures? ✅ Deep dive into Monotonic Stacks (Increasing & Decreasing) ✅ Khandani Template for solving stack-based problems ✅ Brute Force vs Optimal (NSEL, NSER, NGEL, NGER) ✅ Time complexity and key observations 👨‍🏫 With real intuition, visual thinking, and step-by-step coding — this video will simplify what once felt “tough”. 👩‍💻 Who Should Watch? If you’ve struggled with stack problems or find patterns hard to recognize, this is for you! Perfect for interview prep, CP, or leveling up your DSA concepts. 🚀 Master this session, and you’ll start spotting monotonic patterns effortlessly — even in unseen problems 🔥 📌 My Other Playlists My DP Concepts Playlist: https://youtu.be/7eLMOE1jnls My Graph Concepts Playlist: https://youtu.be/5JGiZnr6B5w My Recursion Concepts Playlist: https://www.youtube.com/watch?v=pfb1Zduesi8&list=PLpIkg8OmuX-IBcXsfITH5ql0Lqci1MYPM Trie Playlist: https://www.youtube.com/watch?v=DMP2bqW6URA&list=PLpIkg8OmuX-I99uuP2BZOz4mI_lms4gVG&index=1 Maths Concepts & Qns: https://www.youtube.com/watch?v=-zRQhT1Cdhs&list=PLpIkg8OmuX-J7OdEA2hDjc1V7yvLQXqXc Monotonic Data Structure Concepts & Qns : https://www.youtube.com/playlist?list=PLpIkg8OmuX-IpUPXh3z8oeKSfRkKhjaTV GitHub Repo for Interview Prep: https://github.com/MAZHARMIK/Interview_DS_Algo Instagram: https://www.instagram.com/codestorywithmik/ Facebook: https://www.facebook.com/people/codestorywithmik/100090524295846/ Twitter: https://twitter.com/CSwithMIK Subscribe: https://www.youtube.com/@codestorywithMIK ╔═╦╗╔╦╗╔═╦═╦╦╦╦╗╔═╗ ║╚╣║║║╚╣╚╣╔╣╔╣║╚╣═╣ ╠╗║╚╝║║╠╗║╚╣║║║║║═╣ ╚═╩══╩═╩═╩═╩╝╚╩═╩═╝ 🧠 Summary: In this video, we demystify Monotonic Data Structures and walk through the most used structure: the Monotonic Stack. You’ll learn how to identify when to use it, apply a reusable template, and solve variations like NSEL, NSER, and NGEL, NGER efficiently. With real intuition and no skipping steps, this is a must-watch for acing stack-related DSA problems. ✨ Timelines ✨ 00:00 - Introduction 00:10 - Motivation 00:57 - What is Monotonic Data Structure? 03:16 - What is Monotonic Stack? 03:49 - Monotonic Increasing Stack 06:25 - Khandani Template 11:17 - How does this help?
