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 java.util.Scanner

object Main {
  def main (args: Array[String]) = {
    val in = new Scanner(System.in)
    val a = in.nextInt
    val b = in.nextInt
    val c = in.nextInt

    val div = for (
      i <- 1 to c
      if ((c % i) == 0)
      if (a <= i && b >= i)
    ) yield i

    println(div.length)
  }
}
