Sorting function bug about cpplabs

[potat-dev]

// rewrite compare & sorting functions:

int compare_words(word *w1, word *w2, int reverse) {
  int min_size = w1->size < w2->size ? w1->size : w2->size;
  for (int i = 0; i < min_size; i++)
    if (w1->arr[i] != w2->arr[i])
      return reverse ^ (w1->arr[i] > w2->arr[i]);
  return reverse;
}

void sort_list(list *list, int reverse) {
  for (int i = 0; i < list->size; i++) {
    for (int j = i+1; j < list->size; j++) {
      struct node *node1 = get_node(list, i);
      struct node *node2 = get_node(list, j);
      if (compare_words(node1->word, node2->word, reverse))
        swap_nodes(node1, node2);
    }
  }
}
