>>12717180Correct. Here's another middle school tier problem which if you can't solve you don't belong on /sci/:
Suppose there is a monitor screen showing the view of some camera and a single button which can switch which camera's view you're recording. That is, if you press the button once, the view will now be from a different camera, and so on, until you press it enough times to get back to the original view.
The guard asked to look after the monitor while he went away, and he asked you not to press the button since the current chosen camera will soon record something very important.
While the person was gone, you accidentally broke the screen so you can no longer see which camera you're using. What's more, you accidentally pressed the button to switch the camera view. So now you have the wrong camera on. You desperately need to switch the camera back, but you don't know how many times you need to press the button since you don't know how many cameras there are. All you know is that there aren't more than 6 cameras. Is there a way for you to switch to the original camera with complete certainty despite all of this trouble?
Only IQ>85 can solve this.
