  1. In front of the private departure;
  2. At the bus stop and less than 10 meters before it;

You made plans for the surrounding streets, smashing them into sections the length of 5 meters (this is the minimum length for parking). Land with departure on the plane is denoted by 'D', bus stops - 'B', transitions - 'S', others - '-'. Write a program that for each street will determine the number of parking spaces.
