void print_list(node head)
{
node current = head;
while(current)
{
printf("-> %s ", current->data);
if(!current->next_node) printf("$ n");
current = current->next_node;
}
}
第二段話
void print_list_lazy(node current)
{
if(!current) return;
printf("-> %s %s", current->data, current->next_node? "":"$n");
print_list_lazy(current->next_node);
}
兩段程式都可以做到同樣的效果,但是後者使用的是遞迴。
..所以呢?
遞迴是好物 (飄)
