: The source is the candidate who has no edges pointing to them.
: To ensure the "strongest" preferences are considered first, sort the pairs array in descending order based on the "margin of victory" (the number of people who prefer the winner over the loser). 3. The Locking Logic (Avoiding Cycles) Cs50 Tideman Solution

through any chain of existing locked edges. If a path exists, you skip locking that pair to prevent the cycle. 4. Identifying the Winner The Locking Logic (Avoiding Cycles) A→B→C→Acap A right
The winner in a Tideman election is the "source" of the graph.
This guide breaks down the logical steps required to complete the tideman.c program, focusing on the core functions: vote , record_preferences , add_pairs , sort_pairs , lock_pairs , and print_winner . 1. Validating and Recording Votes The first task is to process each voter's ranked ballot.
