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

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

using System;

public class Program {
 public static void Main(string[] args) {
   string[] stdin = Console.ReadLine().Split(' ');
   
   int num = int.Parse(stdin[0]);
   int train = int.Parse(stdin[1]);
   int taxi = int.Parse(stdin[2]);
   
   if ((num * train) > taxi) {
     Console.WriteLine(taxi.ToString());
   } else {
     Console.WriteLine((num * train).ToString());
   }
 }
}
