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

using System.Threading.Tasks;

class Program {
    static void Main (string[] args) {
          //1000000007

        //int n = int.Parse(Console.ReadLine ());
        string[] p = Console.ReadLine ().Split(' ');
        int n = int.Parse(p[0]);
        int a = int.Parse(p[1]);
        int b = int.Parse(p[2]);
        
        int densya = n * a;
        int ans = 0;


        if(densya >= b){
            ans = b;
        }else{
            ans = densya;
        }


        Console.WriteLine(ans);

    }
