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 extends App {

  val input = readLine().split(" ").map(_.toInt)
  val (a, b, c) = (input(0), input(1), input(2))
  var res = 0

  for(e <- a to b) {
    if (c % e == 0) res += 1 else res
  }

  println(res)
}
