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

using System;

namespace Atcoder_program_test_Csharp
{
    using System;
    class Program
    {
        static void Main(string[] args)
        {
            string[] str = Console.ReadLine().Split(' ');//2つ以上のスペース区切り入力の取得
            int N = int.Parse(str[0]);  //数値で受け取りたい場合は変換する
            int A = int.Parse(str[1]);
            int B = int.Parse(str[2]);
            int A2 = A * N;
            if (B >= A2)
            {
                Console.Write(A2);
            }
            else Console.Write(B);
            Console.ReadKey();
        }
    }
