Question

Suppose that each person in a group of n people votes for
exactly two people from a slate of candidates to fill two
positions on a committee. The top two finishers both win
positions as long as each receives more than n∕2 votes.
a) Devise a divide-and-conquer algorithm that determines
whether the two candidates who received the
most votes each received at least n∕2 votes and, if so,
determine who these two candidates are.
b) Use the master theorem to give a big-O estimate for
the number of comparisons needed by the algorithm
you devised in part (a).
