Locked: Alice→Bob, Bob→Charlie. Testing Charlie→Alice: Start from loser (Alice? No! loser is the second arg? Careful.)
The implementation includes test cases to verify its correctness. For example, consider the following input: Cs50 Tideman Solution
:param candidates: List of candidate names :param voter_preferences: List of voter preferences, where each preference is a list of candidate names in ranked order :return: The winner of the election and the ranked order of the candidates """ # Initialize win counts for each candidate win_counts = candidate: 0 for candidate in candidates Locked: Alice→Bob, Bob→Charlie
I realized I needed a recursive function. The prompt asks: Does locking this pair create a cycle? loser is the second arg
Its goal is to determine a winner in an election using a ranked-choice system that satisfies the Condorcet criterion
The most common voting system used today is plurality voting, where each voter casts one ballot for their preferred candidate. The candidate with the most votes wins. However, this system has several drawbacks. For instance, it can lead to a situation where a candidate wins without receiving a majority of the votes. Additionally, plurality voting can be susceptible to vote-splitting, where similar candidates split the vote, allowing a less popular candidate to win.
That’s wrong — wait! That would be a cycle (Charlie → Alice when Alice → Bob → Charlie already locked). Did we miss it?
