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

Solution in Scala (judge verdict: Accepted)

object Main extends App {
    val sc = new java.util.Scanner(System.in)
    val a, b, c = sc.nextInt
    val pw = new java.io.PrintWriter(System.out)
    pw.println((a to b).toList.filter(c%_ == 0).size)
    pw.flush()
}
