Sorry guys, you failed the interview, and you got the
question wrong. It is what is the least number of
weighings - the answer is 2 not 3.
1) Take 2 random groups of 3 balls, compare them. If they
are the same you got lucky - the heavier ball is the one
you didn't weigh. If they are different you need step 2
2) Take the 3 heavier balls from weighing 1) and randomly
compare 2 of them. If one is heavier, that is the hevier
ball - if tehy are the same, then the one you didn't weigh
is the heavy one.
