Problem Statement

A biscuit making machine produces B biscuits at the following moments: A seconds, 2A seconds, 3A seconds and each subsequent multiple of A seconds after activation.

Find the total number of biscuits produced within T + 0.5 seconds after activation.

Constraints

All values in input are integers.

1 \leq A, B, T \leq 20

Input

Input is given from Standard Input in the following format:

A B T

Output

Print the total number of biscuits produced within T + 0.5 seconds after activation.

Sample Input 1

3 5 7

Sample Output 1

10

Five biscuits will be produced three seconds after activation.

Another five biscuits will be produced six seconds after activation.

Thus, a total of ten biscuits will be produced within 7.5 seconds after activation.

Sample Input 2

3 2 9

Sample Output 2

6

Sample Input 3

20 20 19

Sample Output 3

0

import java.util.Scanner;

public class Main {
		public static void main(String[] args) {
			String str;
			int A, B, T, result = 0;
			Scanner scanner = new Scanner(System.in);

			str = scanner.nextLine();

			A = Integer.parseInt(str.split(" ")[0]);
			B = Integer.parseInt(str.split(" ")[1]);
			T = Integer.parseInt(str.split(" ")[2]);

			for (int i = A; i < T; i = i + A) {
				result += B;
			}

			System.out.println(result);

			scanner.close();
