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.

import java.util.*;

public class Main {
  public static void main(String args[]) {
	Scanner sc = new Scanner(System.in);
	int n = sc.nextInt();
	int a = sc.nextInt();
  int b = sc.nextInt();

	int sumA = a * n;
	int ans;
	if (sumA < b) {
		ans = sumA;
	} 
	else {
		ans = b;
	}
	System.out.println(ans);
}
