STATEMENT
Place the available landmarks to make pathfinding on a given map most efficient.

INPUT
landmarksNum: Number of landmarks to place
efficiency: Minimal average efficiency required to pass the test
width: Width of the map
height: Height of the map
row: A single row of the map consisting of passable terrain ('.') and walls ('#')


OUTPUT
Positions of the landmarks: 'landmarksNum' lines each containing 'column row' coordinates
