Question: 问题:
Find the room with number 1337. Click on 'Save' once you've found it.
找到编号为 1337 的房间。找到后点击“保存”。
Explanation 解释
The numbers are arranged in such a way that taking a left exit brings you to a room with a higher number, and taking the right exit brings you to a room with a lower number. Once you realize this, it is very easy to click correctly and you will find the room you are looking for. Click on the floor to go back one step.
这些数字的排列方式是这样的：从左边的出口出去会进入一个数字更高的房间，从右边的出口出去会进入一个数字更低的房间。一旦你明白了这一点，点击就会变得非常容易，你很快就能找到你要找的房间。点击地板可以后退一步。
Despite the fact that there are actually 511 different rooms, one can find any room with at most 9 clicks. With every click, we can halve the number of remaining rooms. So from 511 we get down to 255, then 127, then 63 and so on down to 1.
尽管实际上有 511 个不同的房间，但最多只需点击 9 次就能找到任何一个房间。每次点击，剩余房间的数量都会减半。所以从 511 个减到 255 个，再减到 127 个，然后是 63 个，以此类推，直到只剩 1 个。
