We need to populate the global pairs array. A pair exists if preferences[i][j] > preferences[j][i] . If equal (tie), skip.
: There is already a path from the new loser to the new winner in the locked graph. If that path exists, adding winner→loser creates a cycle. Cs50 Tideman Solution
: A pair is added to a pairs array if one candidate has more votes than the other.

The first step is to process every voter's ballot. For each voter, the code must update a 2D preferences[i][j] array, where the value at index [i][j] represents the number of voters who preferred candidate i over candidate j . 2. Identify and Sort Matchups
// Find the candidate with the fewest votes int min_votes = MAX_VOTERS; for (int i = 0; i < num_candidates; i++) if (candidates[i].votes < min_votes) min_votes = candidates[i].votes; #include <stdio
: Write a helper function bool creates_cycle(int winner, int loser) or bool has_cycle(int start, int current) .
