50 people have voted in an election, in which they are two candidates, and 25 people
have voted for one candidate, and 25 people have voted for the other. You don’t know
this yet, and are counting the votes, by looking at the ballots in sequence.



What is the number of sequences for which, as you count the votes, neither candidate is ever ahead of the other by more than 15 votes, but the end result is a tie?



I am new to generating functions and trees so would anyone please give me a hint on how to start on this problem?
