Understanding the Algorithm
What is the Rat in a Maze Problem?

Objective: Find a path for the rat to move from the starting point (top-left) to the destination (bottom-right) of a maze.
Conditions: The rat can move only in certain directions (e.g., down, right) and must avoid blocked cells.
How Backtracking Works in This Problem:

Define backtracking: trying all possible paths until the correct one is found.
Steps:
Place the rat in the starting cell.
Move to the next cell based on possible moves (right, down).
If a move leads to a dead-end, backtrack and try another direction.
Example: Use a 4×4 maze to demonstrate a step-by-step solution.
Real-World Application Overview
Navigation Systems:
Autonomous robots navigating unknown terrains or warehouse systems.
Game Development:
Pathfinding for characters in maze-like environments.
AI and Robotics:
Applications in solving physical and virtual mazes.
How the Algorithm Solves the Problem
Problem:

The maze is represented as a 2D matrix with open (1) and blocked (0) cells.
The challenge is to find a safe path from the start to the destination.
Solution:

Use backtracking to explore all paths recursively:
Mark the current cell as part of the path.
Explore moves (e.g., right, down).
If the destination is reached, print the path; otherwise, backtrack.
Challenges in Implementation
Computational Complexity:
Exponential in the worst case, as every cell may need exploration.
Handling Larger Mazes:
Optimizations like memoization or limiting the number of moves can help.
Dynamic Obstacles:
Adapt the algorithm for real-time changes in the maze structure.
Case Study or Example
Example:
A robot navigating a warehouse with a predefined map.
Input: A 4×4 grid where 0 represents obstacles and 1 represents open paths.
Output: Path traced by the robot (e.g., [0,0] → [0,1] → [1,1] → [1,2] → [2,2] → [3,3]).
