show it with code because i dont understand

the current FIFO code is:

    while (1)
        // FIFO
        url_dequeue

        if (descend)
            for (; child; child = child->next)
                url_enqueue
                
the LIFO solution is:

    while (1)
        // LIFO
        url_dequeue

        if (descend)
            // place html pages on top
            ll_bubblesort(&child);
            for (; child; child = child->next)
                url_enqueue
