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

public class Main {
	
  	private static int keisan(int n, int a, int b) {
      
      int j;
      j = n * a;
      
      if (j > b) {
       	return b; 
      } else {
        return j; 
      }
      
    }
  
	public static void main(String[] args) {
        
        
        System.out.println(keisan(4,2,9));
        System.out.println(keisan(4,2,7));
        System.out.println(keisan(4,2,8));
