const readline = require('readline');

const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
});
rl.on('line', function (line) {
    let cur = parseInt(line);
    let path = 0;
    for(let i=0;i <5;i++){
        path += cur
        cur = cur/2;
        path += cur
    }
    console.log(path-cur);// 第五次落地状态
    console.log(cur)
});
