"use strict";

process.stdin.resume();
process.stdin.setEncoding("utf-8");

let inputString = "";

process.stdin.on("data", (inputStdin) => {
    inputString += inputStdin;
});

process.stdin.on("end", (_) => {
    inputString = inputString
    .trim()
    .split("\n")
    .map((str) => str.trim());
    main();
});

function readLine() {
    return inputString[currentLine++];
}

function main() {
    let integers = JSON.parse(readLine());
    /* Please do not modify anything above this line */

    /* Write your code here and log the output */
    const multiple = integers.reduce((a, b) => {
        return a * b
    }, 1)
    
    console.log(multiple)
