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)

import scala.io.StdIn.readLine

object Main {
  def main(args: Array[String]) {
    val Array(a, b, c) = readLine().split(" ").map(_.toInt)
    var i = 0
    (a to b).foreach(j => if(c % j == 0) i += 1)

    println(i)
  }
}
