LeetCode Problem 85 | Maximal Rectangle (11-01-2026) | Using Stack

In this video, I solve LeetCode Problem 85 – Maximal Rectangle, a classic and important problem based on Dynamic Programming and Stack concepts. 🚀 The goal of this problem is to find the largest rectangle containing only 1s in a binary matrix. To solve this efficiently, we convert each row of the matrix into a histogram and apply the Largest Rectangle in Histogram technique using a monotonic stack. By updating heights row by row, we can compute the maximum area in optimal time. This problem helps in understanding how 2D problems can be reduced to 1D, and how stack-based algorithms work in real interview scenarios. It is frequently asked in coding interviews and is a great example of combining multiple concepts together. 📌 Concepts Used: Dynamic Programming Stack (Monotonic Stack) Histogram Technique Matrix Traversal ⏱ Time Complexity: O(rows × cols) 📦 Space Complexity: O(cols) If you’re preparing for coding interviews, DSA, or competitive programming, this problem is a must-watch.
