DSA in Python – Rat in a Maze | Recursion & Backtracking | GFG Problem – Part 81 [Hindi]

🚀 Welcome to Part 81 of Code & Debug’s DSA in Python Course!

In this lecture, we solve the famous Rat in a Maze problem from GeeksforGeeks, where we explore all possible paths a rat can take from the top-left to the bottom-right corner of a maze using Recursion & Backtracking.

📚 What you’ll learn in this video:
✅ Understanding the maze structure and movement rules
✅ Recursive Backtracking to explore all valid paths
✅ Using visited matrix to prevent cycles
✅ Sorting output in lexicographic order as per constraints
✅ Time & space complexity analysis

💡 Why is this important?
This problem is a classic example of grid-based backtracking, useful for solving real-world problems like robot pathfinding, AI navigation, and puzzle solving. It’s a must-practice for FAANG interviews and competitive programming.
