Constraints

1 \leq A \leq 100

1 \leq B \leq 100

All values in input are integers.

Input

Input is given from Standard Input in the following format:

A B

Output

Print the value A \times B as an integer.

Sample Input 1

2 5

Sample Output 1

10

We have 2 \times 5 = 10.

Sample Input 2

100 100

Sample Output 2

10000

Solution in Rust (1.42.0) (judge verdict: Accepted)

use std::io::{self, Read};

macro_rules! input {
    ($it: expr) => ($it.next().unwrap().parse().unwrap());
    ($it: expr, $T: ty) => ($it.next().unwrap().parse::<$T>().unwrap());
}

fn main() {
    let mut buf = String::new();
    io::stdin().read_to_string(&mut buf).unwrap();

    let mut it = buf.split_whitespace();

    let a: u64 = input!(it);
    let b: u64 = input!(it);

    println!("{}", a * b);
}
