Maze of Passages
You are in a maze represented by a 2D grid, where 0 represents an open passage and 1 represents a wall. Starting from the top-left corner (0,0), you need to find all unique paths to the bottom-right corner (n-1,m-1) of the maze. A path can be formed by moving up, down, left, or right. Print all valid paths as lists of coordinates from start to end.
Input:
- First line contains two integers n and m (1 ≤ n, m ≤ 10), the dimensions of the maze.
- Next n lines each contain m integers (0 or 1) representing the maze grid.
Output:
- Print each unique path as a list of coordinates (x, y) from the start to the end, one path per line.
Example:
Input:
3 3
0 0 1
0 0 0
1 0 0
Output:
[(0, 0), (0, 1), (1, 1), (2, 1), (2, 2)]
[(0, 0), (1, 0), (1, 1), (2, 1), (2, 2)]
