Cs50 Tideman Solution ~repack~

// Using bubble sort for simplicity for (int i = 0; i < pair_count - 1; i++)

This article is not just about providing code to copy-paste. It is about understanding why the Tideman solution works, how to avoid the common pitfalls, and how to implement the lock_pairs function and cycle detection correctly. Cs50 Tideman Solution

The vote function updates the ranks array for each voter. Then record_preferences uses those ranks to increment preferences[i][j] for every i ranked higher than j . // Using bubble sort for simplicity for (int

for (int i = 0; i < candidate_count; i++) for (int j = 0; j < candidate_count; j++) preferences[i][j] = 0;
