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

a ≤ b

Sample Input 1

5 14 80

Sample Output 1

3

Solution in JAVA (judge verdict: Accepted)

import java.util.*;


public class Main {
    public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int a = sc.nextInt();
		int b = sc.nextInt();
		int c = sc.nextInt();
		//int z = b - a;
		int cnt = 0;
		for (int i = a; i <= b; i++) {
		    if (c % i == 0) {
		        cnt++;
		    }
		    
		}
		System.out.println(cnt);
    }
}
