With Head node or not? statement is: if(p->rlink != first) p = p->rlink; O a. It is a Doubly linked list without Head node. O b. It is a Doubly linked list with Head node.
The following method is defined within a linked list class. What does it do? void MyList::doSomething() {  Node* p = head;   while (p) {    cout << p->value << " ";    p = p->next;  }} Group of answer choices inserts a node into linked list deletes a node from linked list displays contents of linked list destroys the entire linked list
