Problem:
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.util.*

fun main(args: Array<String>) {
    val argList = Scanner(System.`in`)


    val n = argList.nextInt()
    val a = argList.nextInt()
    val b = argList.nextInt()

    val executor = TorT()
    val result = executor.execute(n, a, b)
    println(result)
}

class TorT {
    fun execute(n: Int, a: Int, b: Int): Int {
        val taxi = b
        val train = n * a

        if (taxi < train) {
            return taxi
        }
        return train
    }
}
