数学题 求路程的时候代入等比数列求和公式 完整代码如下：
const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;
void async function () {
// Write your code here
while(line = await readline()){
let m = parseInt(line);
let res = m + m*(1-(1/2)**4)/(1-(1/2));
let h = (m*(1/2)**5).toFixed(6);
console.log(res);
console.log(h)
}
}()
