231. Invent a game and explain the rules.

You are locked up in 99 floor building. You are in the first floor and there is nothing between first floor and very top floor. Only things that are in the building are 3 switches for a light bulb, elevator, and a light bulb in very top floor. Okay, now you need to find which switch is for the light bulb. Only one switch is the switch for the light bulb. Two other switches are fakes. Wait! You can only use elevator twice; up and down. Remember that there are no stairs, windows, or anything else. Now find which switch is for the light bulb. If first switch is the right one, explain. If second switch is the right one, explain. If third switch is the right one, explain. You need to give me a reason because any three of them can be the right one depends on your reason. Now begin the game!
Is it too hard? Here is my answer. You turn on first and second switches for 30 minutes and turn the second switch off. Then you take an elevator and go up to the top floor. If you see the light on then obviously second switch is the right one. If not, touch the light bulb and see if it is hot or not. If it is hot, then first switch must be the right one because you turned the first switch for a long time and thus, made the light bulb hot. If not hot, then the answer is the third switch because it is cold. So did you now get it? Thank You.
