switch1, switch2 and switch 3
Switch 1 -> he didn't touch that
switch 2 -> he switch it on and wait for 5 min and switch off it
switch 3 -> he switch on it.
Now he goes to the first floor and check which bulb light is turned on it indicates that it related to switch 3. Now he goes and touch the remining two bulbs, switch 2 is on for 5 min so the bulb gets heat, so when he touched the bulb which has some heat he related that bulb with switch 2 then switch 1 related to the bulb which remins cool.
