LC 84. Largest Rectangle in Histogram | Stack HARD | Explained

Welcome to Day 3 of the 75 Hard DSA Challenge In this video, I solve and explain LeetCode 84 – Largest Rectangle in Histogram, a classic HARD problem based on Monotonic Stack. 🔍 What you’ll learn in this video: How to approach histogram problems using stack Next Smaller Element (NSE) and Previous Smaller Element (PSE) method One-pass stack solution Space-optimized approach How to calculate width and area efficiently 🧠 Key Concept: This problem is solved by finding the previous and next smaller elements for each bar to determine the maximum width where a bar can act as the minimum height, and optimizing it into a single-pass monotonic stack solution. 📌 75 Hard sheet: https://docs.google.com/spreadsheets/... 📌 Problem Link: https://leetcode.com/problems/largest... 📌 Solution Link: https://github.com/sibasundarj8/75-Ha...
