Clear the Rooms preparation

Show me that you can solve these problems separately:

1. A jeroo is in a room with a single with no nets (remove the nets for this exercise) and an exit that must be to the east or west. Find the exit. Place a jeroo in each room of a Rooms island and prove it works. It should work no matter where the Jeroo is inside each room or which way it starts out facing.
2. Find a net in a room that is guaranteed to be rectangular with water completely covering the north and south sides and a single one block wide exit on either the east or west side.. Stop when the net has been disabled. Prove it works with 4 Jeroos on a single Rooms island
3. Have a Jeroo traverse the hallway of flowers, starting facing south at the north end of the hall with 4 flowers in its pouch. Have it deposit 1 flower inside of the opening of each room and stop when done
