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 JAVA (judge verdict: Accepted)

import java.util.Scanner;

class Main{

	public static void main(String[] args) {

		int a,b,c;
		int count = 0;

		Scanner stdIn = new Scanner(System.in);

		a = stdIn.nextInt();
		b = stdIn.nextInt();
		c = stdIn.nextInt();

		for(int i = a; i <= b; i++) {

			if((c % i) == 0) {
				count++;
			}
		}

		System.out.println(count);

	}
