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