--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#2,#4,#6,......)并切换它。第三次,访问每个第3门(即3号门,#6号,#9号,......)等,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];

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;
