Question 6
The beavers’ path of light consists of 36 special tiles arranged in a 6×6 grid. Each tile has a lamp that changes state whenever a beaver passes over that tile. A walk starts at the entrance and ends at the exit; each step moves to a tile sharing an edge. After one walk, Alex obtains the pattern below. White lamps are on. “Vào” marks the entrance and “Ra” the exit.
Alex wants to start a new design and first needs to turn all the lamps on. Which of the following walks will do this?
