Aaron the ant walks on the coordinate plane according to the following rules. He starts at the origin p_{0}=(0,0) facing to the east and walks one unit, arriving at p_{1}=(1,0). For n=1,2,3, \ldots, right after arriving at the point p_{n}, if Aaron can turn 90^{\circ} left and walk one unit to an unvisited point p_{n+1}, he does that. Otherwise, he walks one unit straight ahead to reach p_{n+1}. Thus the sequence of points continues p_{2}=(1,1), p_{3}=(0,1), p_{4}=(-1,1), p_{5}=(-1,0), and so o n in a counterclockwise spiral pattern. What is p_{2015} ?
