# Determine the winner winner = ranked_candidates[0]

: For every voter, use a nested loop to compare each candidate in their list to every candidate ranked : If candidate is ranked higher than candidate by a voter, increment preferences[A][B] Dev Genius 3. Create and Sort Pairs

if (from == target) return true; for (int i = 0; i < candidate_count; i++)

Think of the locked array as a directed graph. Each candidate is a node. When you lock a pair (winner → loser), you draw an arrow from the winner to the loser.

if (locked[j][i]) // If someone beats i

The Tideman algorithm works as follows:

To manually test, try a 3-candidate case where a cycle would occur:

// Check if locking this pair (winner -> loser) creates a cycle back to the winner

The distribution code provides a skeleton with these functions: Cs50 Tideman Solution

#define MAX_CANDIDATES 9 #define MAX_VOTERS 9 #define MAX_NAME_LENGTH 50

for (int i = 0; i < pair_count - 1; i++)

return false;

bool is_path(int start, int end)

(Note: The main vote function in tideman.c handles the ranking; this function maps names to IDs). 2. record_preferences Function

: Validates the candidate's name and records their rank.

is_source = false; break;
