You own a warehouse which is a 7x7 grid of cells. You must arrange a maximal number of boxes in the warehouse so that you are able to travel to any given cell. Here are the specific conditions:
- You start at the top left cell.
- You may not occupy the same cell as a box, and all boxes must be in distinct cells.
- You are allowed to move to an adjacent cell if it's free, or if you can push the box(es) in your way.
- You are not required to visit every cell. You are simply required to be able to visit any given cell from the initial configuration.
