Score : 100 points

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: Wrong Answer)

#include <stdio.h>

int main(void)
{
    int num,train,taxi;

    printf("人数：　");
    scanf("%d",&num);

    printf("電車賃：　");
    scanf("%d",&train);
    
    printf("taxi: ");
    scanf("%d",&taxi);
    
    if(num*train<taxi||num*train==taxi){
        printf("%d\n",num*train);
    }
    else if(num*train>taxi){
        printf("%d\n",taxi);
    }
   

}
