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

object Main{
  def main(args: Array[String]){
    val line = StdIn.readLine.split(" ").toList.map(_.toInt)

    println((line.head to line.tail.head).map{i => line.last % i == 0}.filter{_ == true}.length)
  }
}
