Problem I. Ivan and the swimming pool
*****
Announcement
The pool does not need to be rectangular, the only requirement is that it is a connected group of cells. Two cells are adjacent if they share a side. A group of cells is said to be connected if for any pair of its cells, you can move from one to another by following a path of adjacent cells.
