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)

object Main {
  def main(args: Array[String]) = {
    import scala.io.StdIn.readLine

    /*
    val sc = new java.util.Scanner(System.in)
    val A = sc.nextInt
    val B = sc.nextInt
    val T = sc.nextInt
    sc.close()

    val createCount = Math.floor((T + 0.5) / A).toInt
    val createNum = createCount * B
    println(createNum)
     */

    val Array(a, b, t) = readLine.split(" ").map(_.toInt)
    val count = t / a * b
    println(count)
  }
