Problem:
How Many Divisors?

Write a program which reads three integers a, b and c, and prints the number of divisors of c between a and b.

Input

Three integers a, b and c are given in a line separated by a single space.

Output

Print the number of divisors in a line.

Constraints

1 ≤ a, b, c ≤ 10000

a ≤ b

Sample Input 1

5 14 80

Sample Output 1

3

Solution in Scala (judge verdict: Accepted)

object Main extends App {
    val ary = io.StdIn.readLine().split(" ").map(_.toInt)
    val list = Range(ary(0), ary(1)+1)
    println(list.map(ary(2)%_).count(_==0))
}
