--description--

连续100个门都是最初关闭的。你可以在门口进行100次通行证。第一次通过访问每扇门并“切换”门如果门关闭打开它;如果它打开关闭它。第二次只访问每个第二个门即门246......并切换它。第三次访问每个第3门即3号门6号9号......直到您只访问第100个门。

实现一个功能,以确定最后一次通过后门的状态。将最终结果返回到数组中,如果数组打开,则只包含数字中包含的门号。

--hints--

getFinalOpenedDoors是一个函数。

assert(typeof getFinalOpenedDoors === 'function');

getFinalOpenedDoors应该返回一个数组。

assert(Array.isArray(getFinalOpenedDoors(100)));

getFinalOpenedDoors没有产生正确的结果。

assert.deepEqual(getFinalOpenedDoors(100), solution);

--seed--

--after-user-code--

const solution = [1, 4, 9, 16, 25, 36, 49, 64, 81, 100];

--seed-contents--

function getFinalOpenedDoors(numDoors) {

}

--solutions--

function getFinalOpenedDoors(numDoors) {
  // this is the final pattern (always squares).
  // thus, the most efficient solution simply returns an array of squares up to numDoors).
  const finalState = [];
  let i = 1;
  while (Math.pow(i, 2) <= numDoors) {
    finalState.push(Math.pow(i, 2));
    i++;
  }
  return finalState;
}
