3 Light Bulbs 3 Switches
There is a lightbulb inside a cupboard. The door is closed, and you cannot run across if the light is on or off through the door. However, you know the lite is off to get-go.
Outside of the cupboard, there are three light switches.
One of the door lite switches controls the lightbulb in the closet. You can flip the switches however you lot desire, but in one case you open the door, you can no longer touch the switches.
How do you figure out without a doubt which of the three light switches controls the light?

Retrieve most information technology for a infinitesimal, then coil down...

Fix for the respond?

Here it is:
Flip switch number one and expect a few minutes. Flip switch number ane back to its original position, and then immediately flip switch number 2.
Open up the door. If the light is on, then switch number 2 controls it. If the lite is off, and so go and feel the bulb with your paw. If the bulb is hot, and then switch number 1 controls information technology, and if the bulb is cold, and then switch number 3, the one you lot did not touch, controls it.
