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: Accepted)

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

int main(){
	int i;
//	char s[4];

//	for(i=0;i<4;i++) scanf("%c",&s[i]);
  int N, A, B;
//int *agi;int min = 1000;
  scanf("%d",&N);
  scanf("%d",&A);
  scanf("%d",&B);

  double y = fmin(N*A, B);

  printf("%d", (int) y);

  return 0;


/*
	for(i=0;i<3;i++){
		if(s[i]==s[i+1]){
			printf("Bad\n");
			return 0;
		}
	}
	printf("Good\n");*/
