const order = (chicken) => {

  const service = Math.floor(chicken / 10);
  return service + order(service + (chicken % 10));
};

const solution = (chicken) => {
  const answer = order(chicken);
  console.log(answer);

  return answer;
};

 

솔루션

const solution = (chicken) => {
  let answer = 0;
  let coupon = chicken;

  while (coupon >= 10) {
    answer = answer + parseInt(coupon / 10);
    coupon = parseInt(coupon / 10) + (coupon % 10);
  }
  console.log(answer);

  return answer;
};
