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
import Math.sqrt

object Main {

  def main(args: Array[String]) = {
      val n = readLine.split(" ").map(_.toInt)
      var cnt = 0
      for(i <- n(0) to n(1))
          if(n(2) % i == 0)
              cnt += 1
      println(cnt)
  }
}
