count_first_place_votes(voters_prefs, voters, candidates_list, candidates);

The implementation involves the following functions: #include <stdio.h> #include <stdlib.h>

// Read in voter preferences for (int i = 0; i < *voters; i++) { (*voters_prefs)[i].preferences = malloc(*candidates * sizeof(int)); for (int j = 0; j < *candidates; j++) { scanf("%d", &(*voters_prefs)[i].preferences[j]); } } }

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

candidate_t *candidates_list = malloc(candidates * sizeof(candidate_t)); for (int i = 0; i < candidates; i++) { candidates_list[i].id = i + 1; }

// Function to count first-place votes void count_first_place_votes(voter_t *voters_prefs, int voters, candidate_t *candidates_list, int candidates) { // Initialize vote counts to 0 for (int i = 0; i < candidates; i++) { candidates_list[i].votes = 0; }

eliminate_candidate(candidates_list, candidates, eliminated);
