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.

using System;

namespace abc133_a
{
    class Program
    {
        static void Main(string[] args)
        {
            var items = Console.ReadLine().Split(' ');
            // 人数
            var n = int.Parse(items[0]);
            // 電車 %1
            var a = int.Parse(items[1]);
            // タクシー %n
            var b = int.Parse(items[2]);

            var c = Math.Min(a * n, b);

            Console.WriteLine($"{c}");
        }
    }
}
