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.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {
	
	public static void main(String[] args) {
		try {
			BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));

			String str = reader.readLine();
			String[] arr = str.split(" ");
			int a = Integer.parseInt(arr[0]);
			int b = Integer.parseInt(arr[1]);
			int c = Integer.parseInt(arr[2]);
			int cnt = 0;
			
			for (int i = a; i <= b; i++) {
				if (c % i == 0) {
					cnt++;
				}
			}
			System.out.println(cnt);
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
