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 Rust (1.15.1) (judge verdict: Accepted)

fn main() {
	let mut line = String::new();
	let _ = std::io::stdin().read_line(&mut line);
	let vec: Vec<&str> = line.split_whitespace().collect();
	let n:i32 = vec[0].parse().unwrap();
	let a:i32 = vec[1].parse().unwrap();
	let b:i32 = vec[2].parse().unwrap();

	println!("{}", std::cmp::min(n * a, b));
}
