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]) : Unit = {
        val input = io.StdIn.readLine().split(" ").map(_.toInt)
        var count = 0
        for (i <- input(0) to input(1)) {
            if ((input(2) % i) == 0)
                count += 1
        }
        println(count)
    }
}
