Score : 100 points

Problem Statement

N of us are going on a trip, by train or taxi.

The train will cost each of us A yen (the currency of Japan).

The taxi will cost us a total of B yen.

How much is our minimum total travel expense?

Constraints

All values in input are integers.

1 \leq N \leq 20

1 \leq A \leq 50

1 \leq B \leq 50

Input

Input is given from Standard Input in the following format:

N A B

Output

Print an integer representing the minimum total travel expense.

Sample Input 1

4 2 9

Sample Output 1

8

The train will cost us 4 \times 2 = 8 yen, and the taxi will cost us 9 yen, so the minimum total travel expense is 8 yen.

Sample Input 2

4 2 7

Sample Output 2

7

Sample Input 3

4 2 8

Sample Output 3

8

Solution in Kotlin (1.0.0) (judge verdict: Accepted)


import java.io.PrintWriter
import java.lang.Math.min

fun solve(out: PrintWriter): Boolean = with(out) {
    val arg = readLine()!!.split(" ").map{it.toInt()}
    println(min(arg[1]*arg[0], arg[2]))
    return false
}

// with(PrintWriter(System.out))
// with(File("out.txt").printWriter())
// with(File(args[1]).printWriter())
fun main(args: Array<String>) = with(PrintWriter(System.out)){
//    System.setIn(File(args[0]).inputStream())
    while(solve(this));
    flush()
}
