A neat little trick to handle deletes for a priority_queue STL - use another priority_queue, say, del_pq. Keep inserting all the delete values to this. When you are popping values from the original priority queue, check with top of del_pq and see if we wanted to delete it. If it matches, delete the value from the original priority_queue.
