Data Structures and Algorithms with Python | Free DSA with Python Course - DSA in Python - Minimum Path Sum | 4 Grid DP Approaches | LeetCode 64 | Part 198 [Hindi]

📘 Welcome to Part 198 of Code & Debug’s DSA in Python Course! In this episode, we master the essential Minimum Path Sum problem from LeetCode, a classic grid-based dynamic programming challenge! Learn how to find the path from top-left to bottom-right in a grid so the sum of all numbers along the way is minimized. We will walk you through all 4 major DP techniques, evolving step by step from brute force recursion to the space-optimized solution, with complete guidance drawn from our detailed article. This is a must-learn for every aspiring coder aiming to ace grid DP questions in coding interviews! 🏫 What’s covered in this video: 1. Problem statement with illustration and key constraints 2. Approach 1: Brute Force Recursion 3. Approach 2: Memoization (Top-Down DP) 4. Approach 3: Tabulation (Bottom-Up DP) 5. Approach 4: Space-Optimized Tabulation 6. Step-by-step Python code for each technique 7. Dry runs and transition mapping for intuition 8. Time & space complexity for each approach 9. Interview tips, how to think about grid state transitions After this session, you’ll confidently handle a full suite of grid DP patterns, preparing you for both beginner and advanced coding assessments! 🔗 LeetCode Problem – Minimum Path Sum: https://leetcode.com/problems/minimum-path-sum/description/ 🔗 In-Depth Article with Codes & Explanations: https://codeanddebug.in/blog/minimum-path-sum/ 📄 FULL Playlist Sheet (Every Video Listed): https://docs.google.com/spreadsheets/d/1AWE15Fy3wD2iqu2vjK_R7cCiuvSsjYQclcdZmHpF66o/edit?usp=sharing 🎓 Enroll Free: Master Python DSA Course https://codeanddebug.in/course/master-dsa-with-leetcode 🚀 Advance Python DSA for FAANG (Zero to Hero Course): https://codeanddebug.in/course/zero-to-hero-python-dsa Stay focused and keep coding with Code & Debug.
