Given a reference that points to a node $x$ in a doubly circular linked list. Please write a pseudocode function to delete the node $x$ from the doubly circular linked list. No return values are expected. Note: A node in a doubly circular linked list has two pointers, named 'next' and 'prev', respectively, where the 'next' pointer is used to find the next node and the 'prev' pointer is used to find the previous one.
