    Approach:
    - Find start position
    - Count number of visitable nodes in the grids
    - A path is only valid if we read end node && all visitable nodes have been visited
    - Perform dfs, everytime we visit a cell, we mark as visited. 
    - We cannot visit a cell more than once
    - Handle boundary edge cases too
