// If loser directly points to winner, cycle is immediate if (loser == winner)

void sort_pairs(void) for (int i = 0; i < pair_count - 1; i++) for (int j = 0; j < pair_count - i - 1; j++) // Compare margins: pairs[j] vs pairs[j+1] int margin1 = preferences[pairs[j].winner][pairs[j].loser] - preferences[pairs[j].loser][pairs[j].winner]; int margin2 = preferences[pairs[j+1].winner][pairs[j+1].loser] - preferences[pairs[j+1].loser][pairs[j+1].winner]; if (margin1 < margin2) // Swap pairs pair temp = pairs[j]; pairs[j] = pairs[j+1]; pairs[j+1] = temp; Use code with caution. 5. lock_pairs Function (The Hardest Part) Cs50 Tideman Solution

void print_winner(void) for (int i = 0; i < candidate_count; i++) bool has_pointer = false; for (int j = 0; j < candidate_count; j++) if (locked[j][i]) has_pointer = true; break; if (!has_pointer) printf("%s\n", candidates[i]); return; Use code with caution. Key Takeaways and Debugging // If loser directly points to winner, cycle

// Eliminate the candidate eliminated_candidates++; candidates[min_vote_index].votes = -1; i // Eliminate the candidate eliminated_candidates++
