Rat in a Maze: All Paths Problem

You are provided with an N * N maze where a rat is positioned at starting cell MAZE[0][0]. The goal is to determine and print all possible paths that the rat can take to reach its destination at MAZE[N-1][N-1]. The rat can move in any of the four cardinal directions: left, right, up, or down.

The maze's configuration is such that each cell holds a binary value, where 0 represents a blocked cell that the rat cannot traverse, and 1 signifies an open cell.

Input:

An integer N indicating the dimension of the maze.
Following this, there are N lines, each containing N space-separated integers indicating the cell type (0 or 1).

Output:

For every test case, return the path from the starting position to the destination. In each path's representation, only the cells that constitute the path should have a value of 1, while all others should be 0.
Output for each test case should be on a new line.

Example:

Input:
N = 4
MAZE = [[1, 1, 0, 0],
[1, 1, 1, 0],
[0, 1, 0, 0],
[1, 1, 1, 1]]
Output:
[
[1, 1, 0, 0],
[0, 1, 0, 0],
[0, 1, 0, 0],
[0, 1, 1, 1]
]
(Other valid paths may also be printed)

Constraints:

  • 1 <= N <= 10
  • 0 <= MAZE[i][j] <= 1
  • Time Limit: 1 sec
Note:
You do not need to print anything, it is already handled. Implement the specified function to return the answer.

Find all possible paths for a rat in a maze from start to finish.

  • Use backtracking to explore all possible paths in the maze.

  • At each cell, check if it is a valid move and mark it as part of the path.
