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

function Main(input){
  input = input.split("\n");
  inputStr = input[0].split(" ");
  var N = Number.parseInt(inputStr[0]);
  var A = Number.parseInt(inputStr[1]);
  var B = Number.parseInt(inputStr[2]);
  //AとBの小さい値に人数を掛けて計算する
  console.log(Math.min(A,(B/N)) * N);
}
Main(require("fs").readFileSync("/dev/stdin", "utf8"));
