Inital position + 4 times rotate in one direction = initial position.
Therefore 6 times left = 6-4 = 2 times left and 7 times right = 3 times right
Total shift from initial position = 2 left + 3 right + 2 left = 4 left + 3 right = 1 left from initial
if final = south, then initial = south - left = south + right = West
