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

            if ((a[0] * a[1]) < a[2]) { Console.WriteLine(a[0] * a[1]); }
            if ((a[0] * a[1]) > a[2]) { Console.WriteLine(a[2]); }
            if ((a[0] * a[1]) == a[2]) { Console.WriteLine(a[0] * a[1]); }
        }
