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

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

using System;
 
namespace Sample
{
  class Sample
  {
    static void Main(string[] args)
    {
    string[] input =Console.ReadLine().Split(' ');
      int N=int.Parse(input[0]);
	int A=int.Parse(input[1]);
      int B=int.Parse(input[2]);
    
      if(N*A>=B){
        Console.WriteLine(B);
      }else{
      Console.WriteLine(N*A);
      }
  }
