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.

Solution in JavaScript (node.js v5.12) (judge verdict: Accepted)

function main(input) {
    input = input.split(' ').map(Number);
    var N = input[0];
    var A = input[1];
    var B = input[2];
    if(N * A <= B){
        console.log(N*A);
    } else {
        console.log(B);
    }
}
main(require('fs').readFileSync('/dev/stdin', 'utf8'))
