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 n, a, b;
    
        char buf[256];
        fgets(buf,256,stdin);
        sscanf(buf, "%d %d %d", &n, &a, &b);
         printf("%d\n", n);
          printf("%d\n", a);
           printf("%d\n", b);
        if( n < 1| n > 20| a < 1| a > 50| b < 0| b >50){
            return 0;
        }else{
            
            int m;
            m = a * n;
             printf("%d\n", b);
            printf("%d\n", m);
            if(m > b){
                printf("%d\n", b);
            }else{
                printf("%d\n", m);
            }
        }

    return 0;
