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

Solution in C# (Mono 4.6.2.0) (judge verdict: Accepted)

using System;

public class Program{
    public static void Main(){
        string[] input=Console.ReadLine().Split(' ');
        int N=int.Parse(input[0]);
        int A=int.Parse(input[1]);
        int B=int.Parse(input[2]);
        int sumA=A*N;
        int ans=0;
        if(sumA>=B){
            ans=B;
        }else{
            ans=sumA;
        }
        Console.WriteLine(ans);
    }
}
