Cs50 Tideman Solution

if (preferences[i][j] > preferences[j][i])

// Global arrays int preferences[MAX][MAX]; bool locked[MAX][MAX];

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

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

The algorithm would then rank the candidates as follows:

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

if (locked[j][i])

through any chain of existing locked edges. If a path exists, you skip locking that pair to prevent the cycle. 4. Identifying the Winner

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

if (will_create_cycle(winner, i)) return true; Cs50 Tideman Solution

Alex had conquered the simple election, but Tideman was a different beast. The CS50 curriculum demanded a more sophisticated winner—a candidate who could win head-to-head battles without creating an infinite loop of confusion. The Strategy To defeat the beast, Alex had to master several weapons:

: Use a nested loop over the ranks array. For every candidate in the voter's list, they are preferred over every candidate that appears after them. Increment preferences[i][j] accordingly. 3. Add Pairs
