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

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>

int main()
{
	int D, N, A, B;

	printf("何人で旅行しますか\n");
	scanf("%d", &N);

	printf("1人あたりの電車代を入力してください\n");
	scanf("%d", &A);

	printf("%d人のタクシー代を入力してください\n", N);
	scanf("%d", &B);

	D = N * A;

	if (D > B) {
		printf("最小合計交通費は%d円です\n", D);
	}
	else {
		printf("最小合計交通費は%d円です\n", B);
	}

	return 0;
