Cs50 Tideman Solution

recount_votes(voters_prefs, voters, candidates_list, candidates);

The winner is: 1 This indicates that candidate 1 wins the election. Cs50 Tideman Solution

Tideman is a voting system implemented in the CS50 course, where voters rank candidates in order of preference. The goal of the Tideman solution is to determine the winner of an election based on the ranked ballots. In this report, we will outline the problem, provide a high-level overview of the solution, and walk through the implementation. In this report, we will outline the problem,

// Structure to represent a voter typedef struct voter { int *preferences; } voter_t; In this report

int main() { int voters, candidates; voter_t *voters_prefs; read_input(&voters, &candidates, &voters_prefs);

int winner = check_for_winner(candidates_list, candidates); while (winner == -1) { // Eliminate candidate with fewest votes int eliminated = -1; int min_votes = voters + 1; for (int i = 0; i < candidates; i++) { if (candidates_list[i].votes < min_votes) { min_votes = candidates_list[i].votes; eliminated = candidates_list[i].id; } }

// Function to eliminate candidate void eliminate_candidate(candidate_t *candidates_list, int candidates, int eliminated) { // Decrement vote counts for eliminated candidate for (int i = 0; i < candidates; i++) { if (candidates_list[i].id == eliminated) { candidates_list[i].votes = 0; } } }
