Problem:
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(){
    int N;
    int A;
    int B;
    int min = 0;

    1<=N<=20;
    1<=A<=50;
    1<=B<=50;

    printf("N:");
    scanf("%d",&N);
    printf("A:");
    scanf("%d",&A);
    printf("B:");
    scanf("%d",&B);
    
  
    if(A * N <= B){
        min = A * N;
    }else{
        min = B;
    }

    printf("min:");
    printf("%d", min);

}
