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

Solution in Scala (2.11.7) (judge verdict: Accepted)

import scala.math.{min,max}

object Main {
    def main(args: Array[String]) {
        var input = io.Source.stdin.getLines().mkString("\n");
        var ss = input.split('\n').toList;
        val xs = to_array_int(ss(0));
        val a = xs(0);
        val b = xs(1);
        val t = xs(2);
        val res = t / a * b;
        println(res);
    }
    def to_array_int(s: String): Array[Int] = {
        return s.split(' ').map(_.toInt).toArray;
    }
