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: Runtime Error)

#include<stdio.h>
int main(){

  int A,B,N; 
  int sum1,sum2,min;
  1 <= N <=20;
  1 <= A <=50;
  1 <= B <=50;
  sum1 = A*N;
  sum2 = B*N;

  scanf("%d,%d,%d\n", N,A,B);
  if (sum1 >= sum2) {
    min = sum2;
    printf("%d\n", min);
  }
  else
   min = sum1;
   printf("%d\n", min);

   return 0;
