数学不好的人的思路😁
按题目描述去写
代码
const getData = h => {
return [(h * 1.5).toFixed(6), (h * 0.5).toFixed(6)]
}
while(h = ~~readline()) {
let count = 5;
let total = 0;
let lastH = h;
while(count--) {
const [_t, _h] = getData(lastH);
total += Number(_t);
lastH = Number(_h);
}
console.log(total - lastH);
console.log(lastH);
}
