C Programming

Now, both datatypes can be combined to build complex algorithms as illustrated below:

GNode* build(GString* val, char deep, GList* visited) {
  GNode* node = g_node_new(val);
  if (deep>0) {
    for (int i=0; i<MAXI; i++) {
      if (g_list_index(visited,GINT_TO_POINTER(i))==-1) {
        GString* newval = g_string_new(val->str);
        g_string_append_c(newval,i+'0');
        GList* newvisited = g_list_copy(visited);
        newvisited = g_list_append(newvisited,GINT_TO_POINTER(i));
        g_node_append(node,build(newval,deep-1,newvisited));
      }
    }
  }
  return node;
}

void main() {
  GNode* root = build(g_string_new(""),MAXI,NULL);
  g_node_traverse(root, G_LEVEL_ORDER, G_TRAVERSE_LEAVES,-1,prn,NULL);
  g_print("\n");
}
