LeetCode 1219 | Path with Maximum Gold | Python Backtracking DFS Explained | AlgoYogi

Welcome to AlgoYogi! 🚀 Start Your Smart Coding Prep at 👉 https://algoyogi.io In this video, we solve **LeetCode 1219: Path with Maximum Gold** using Python and a **backtracking DFS** approach. The idea is to explore all possible paths starting from any gold-containing cell, collect gold along the way, mark visited cells (temporarily set to 0), and backtrack. The goal: find the maximum total gold collectible without revisiting cells. 👉 Problem Link: https://leetcode.com/problems/path-with-maximum-gold/ --- ### ​ Timestamps 0:00 Introduction 0:20 Problem Statement 0:40 DFS + Backtracking Approach 12:00 Python Code Walkthrough 19:30 Time & Space Complexity --- ### Why Watch? - Learn how to **use backtracking DFS** to explore all valid paths exhaustively - See how **in-place marking** keeps code clean without extra data structures ([walkccc.me](https://walkccc.me/LeetCode/problems/1219/?utm_source=chatgpt.com)) - Understand why **greedy fails**—only full exploration guarantees correctness ([medium.com](https://medium.com/%40vikasg_65078/leetcode-daily-problem-1219-path-with-maximum-gold-may-14-2024-996e191bb91f)) --- 📢 Next Steps: - Try related DFS grid problems on [AlgoYogi.io](https://algoyogi.io) - Comment with your own optimized Python snippet or edge-case paths! #LeetCode #PathWithMaximumGold #DFS #Backtracking #Python #AlgoYogi #GridBacktracking
