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)

object Main{
  def check(a:Int, b:Int, c:Int) = {
    var d:Int = 0
    for(i <- a to b){
      if(c % i == 0)
        d += 1
    }
    println(d)
  }
  def main(args:Array[String]) = {
    val scanner = new java.util.Scanner(System.in)
    val a = scanner.nextInt
    val b = scanner.nextInt
    val c = scanner.nextInt
    check(a, b, c)
  }
}
