Formula

  • Number of people in the queue = Number of people ahead + 1 person under consideration + number of people behind
  • If a person's position is x from start, there are x-1 people ahead of him
  • If a person’s position in a queue is x from the front and y from the last, then the total number of people in the queue is x+y-1.
  • If a person A’s rank from the front of the queue is x, a person B’s rank from the back of the queue is y, and the number of people in the queue is p, then the number of people between A and B is equal to p-x-y.
