A blindfolded man is asked to sit in the front of a carrom
board. The holes of the board are shut with lids in random
order, i.e. any number of all the four holes can be shut or
open.

Now the man is supposed to touch any two holes at a time and
can do the following.

? Open the closed hole.

? Close the open hole.

? Let the hole be as it is.

After he has done it, the carrom board is rotated and again
brought to some position. The man is again not aware of what
are the holes which are open or closed.

How many minimum number of turns does the blindfolded man
require to either open all the holes or close all the holes?

Note that whenever all the holes are either open or close,
there will be an alarm so that the blindfolded man will know
that he has won.
