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 main(args: Array[String]) {
     val list = readLine().split(" ").map(_.toInt)
     val (a, b, c) = (list(0), list(1), list(2)) 
     var count = 0
     for (i <- a to b) {
       if (c % i == 0) count += 1   
     }
     println(count)
  }
}
