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]): Unit = {
    val sc = new java.util.Scanner(System.in)
    val a, b, c = sc.nextInt
    var ans = 0
    for (i <- a to b; if c % i == 0) {
      ans += 1
    }
    println(ans)
  }
}
