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

Solution in Scala (judge verdict: Accepted)


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