The candidate with the highest number of votes wins the election. If two or more candidates have the same number of votes, then the tied candidates' names are ordered alphabetically and the last name in the alphabetical order wins. For example, votes are in the names ['Joe', 'Mary', 'Mary', 'Joe']. Each candidate received two votes, but Mary is alphabetically later than Joe, so she wins.

The function must return a string denoting the name of the winning candidate. electionWinner has the following parameter(s): votes[votes[0],...votes[n-1]]: an array of strings representing the names of the candidates as voted by the ith voter.
