Accepted Answer

This is a classic puzzle known as the "Three Switches and Three Bulbs" problem. Here's how you can solve it:

Turn on one switch (let's call it Switch 1) and leave it on for a few minutes.
After some time, turn off Switch 1 and turn on another switch (Switch 2).
Immediately enter the room with the bulbs.
Now, here's what you'll observe:

If one of the bulbs is lit up, that bulb is connected to Switch 1.
If one of the bulbs is warm (but not lit up), that bulb is connected to Switch 2.
The third bulb, which is neither lit nor warm, is connected to Switch 3.
This method works because:

The bulb that is lit corresponds to the switch that was turned on and left on (Switch 1).
The warm bulb corresponds to the switch that was turned on and then turned off (Switch 2), as the bulb retains some heat.
The bulb that is neither lit nor warm corresponds to the switch that was never turned on (Switch 3).
