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

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;
public class Main {
  public static void main(String[] args) {
    Scanner s = new Scanner(System.in);
    int a = s.nextInt();
    int b = s.nextInt();
    int c = s.nextInt();
    int divisors = 0;
    for (int i = a; i <= b; i++) {
      if (c % i == 0)
        divisors++;
    }
    System.out.println(divisors);
  }
}
