View as PDFIn a land with developed democracy far, far away, presidential elections for the football
association are taking place. This land consists of  counties, and each county has its own
football association. There are 
 presidential candidates labeled with

football associations will select exactly one candidate to cast their vote for. The winner of the
election is the candidate with the most votes. If multiple candidates get the most amount of
votes, the winner is the one with the smallest label.
During the election campaign, candidates visited the counties and tried to gain their sympathies. After having met all the candidates, each county's football association determined the order in which they would cast their vote for each candidate.
For example, let's assume that there are four candidates in the election and that one
county's order is . This means that, unless they revoke their candidacy, the
candidate with label 
 will get the county's vote. If candidate 
 revokes their candidacy, and
candidate 
 is still in the race, then they will get the vote, and so on.

wants to know which candidate will win if none of the candidates revoke their candidacy.
