Data Structures and Algorithms with Python | Free DSA with Python Course - DSA in Python - Cherry Pickup II | 3D DP for 2 Robots | LeetCode 1463 | Part 201 [Hindi]

📘 Welcome to Part 201 of Code & Debug’s DSA in Python Course! In this video, we take on Cherry Pickup II from LeetCode, a truly classic advanced DP challenge involving 2 robots traversing a grid to collect the maximum cherries! Both robots start at opposite corners of the top row and move to the bottom row, with only down/diagonal moves allowed. We'll explore all core approaches, from brute-force recursion to fully optimized 3D dynamic programming, matching the clarity and breakdowns given in our comprehensive blog article. This problem is key for mastering 3D DP, state design with multiple actors, and handling overlapping cell visits, a favorite in competitive coding and tough interviews! 👨🏫 What’s covered in this video: 1. Full problem statement, grid constraints, and sample walkthroughs 2. Approach 1: Recursion with backtracking for both robots 3. Approach 2: Memoization (Top-Down 3D DP) 4. Approach 3: Tabulation (Bottom-Up 3D DP) 5. Approach 4: Space-optimized DP for large grids 6. 3D DP state definition: f(row, col1, col2) 7. Performance, time & space complexity analysis By the end, you'll be ready to tackle multi-agent grid DP problems and ace similar patterns in contests and interviews! 🔗 LeetCode Problem – Cherry Pickup II: https://leetcode.com/problems/cherry-pickup-ii/description/ 🔗 In-Depth Article with Code & Explanations: https://codeanddebug.in/blog/cherry-pickup-ii/ 📄 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.
