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 (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>
int main(void)
{
    int n, a, b;
    scanf("%d %d %d", &n, &a, &b);
    if((1 <= n)&&(n <= 20)&&(1 <= a)&&(a <= 50)&&(1 <= b)&&(b <= 50))
    {
        int train, taxi;
        train = n * a;
        taxi = b;
        if(train < taxi) printf("%d", train);
        else             printf("%d", taxi);
    }
}
