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 (Clang 3.8.0) (judge verdict: Accepted)

#include<stdio.h>
#include<string.h>
#include<math.h>

#define FOR(n) for(int i=0;i<n;i++)
#define PRN(n) printf("%d\n",n)
#define PRS(s) printf("%s\n",s)
#define PRC(c) printf("%c\n",c)
int min(int a,int b){
  if(a>b)return b;
  return a;
}
int main(void){
  int n,a,b;
  scanf("%d %d %d",&n,&a,&b);
  PRN(min(n*a,b));
  return 0;
