const readline = require('readline');

const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
});

function lukujono(intOrigin){
    let integer = Math.float(intOrigin);
    while (intOrigin != 1) {
        if (intOrigin % 2 == 0) {
            intOrigin = intOrigin / 2;
        } else {
            intOrigin = 3 * intOrigin + 1;
        }
        console.log(intOrigin);
    }
    console.log(1);
};

rl.question("", (int) => {
