Given an N * N maze with binary values, find and print all possible paths for a rat to reach the destination cell.
Use backtracking to explore all possible paths from the starting cell to the destination cell.
At each cell, check if it is a valid move (within bounds and not blocked), then recursively explore all four directions.
Keep track of the path taken so far and mark the cells accordingly.
Once the destination cell i...
