A passenger jet leaves from John C. Munro International Airport in Hamilton, Ontario and flies on a straight path until it reaches its destination. When it begins its flight, it will be seen by the radar tower located at Munro Airport. Along its path, it will pass by other airports, each with its own radar tower. In some cases, the airplane will pass close enough to be seen, in others it won't. Your task is to determine how many radar screens the airplane will appear on during its flight.
The input will contain five sets of data. The first line of each set contains integers
Write a program that will read each test case and print out the number of radar towers that will see the jet at some point during its flight.
