1 Trial:
Take 3 set of 3balls and first compare any 2
set.They may are may not be equal.If thet are equal keep
these 2 sets aside and go to second trial with the 3rd set.
If they r not equal,go to second trial with the set of more
weight.
2 Trial:
Split the taken set of 3 balls in to 3 set of single
balls.Compare any one sets first.If they are equal we can
find the left out ball is of more weight.If not equal we
can find the most weight ball.
