Because 1 + 2 = 3 :)

U can use integer type for them, btw, the range of numbers
of route is 1000

No, it's not!
Starting thinking of this problem i mentioned, that there's
nothing said about the numbers of the routes. Are they
Integer, Word or Longint?
I do think, that's a mistake of the creators.
Alright, you say i can use integer to store them. But as i
can see, some of them are greater, than 1000!
Perhaps, it doesn't matter for you, but it does matter for
me, because i just solved if using a primitive Deikstra
algorithm for shortest paths. And i do need to know the
range of route numbers.
