Transcribed Image Text:Please help to fill the blank statements to complete the Append function of Doubly linked list, which
has Head node(Dummy head node).
typedef struct Node {
int data;
struct Node *next;
struct Node *prev;
} Node;
void append(int x) {
// current is pointing to first element, we iterate until we find the end
// Head is a Global variable, which pointer to the Head node with Empty data of Doubly linked list
Node* current = Head;
while(current->next !=
current = current->next;
) {
}
// create a new Node and append the item into the end of list
current->next = (Node *)malloc(sizeof(Node));
current->next->data = x;
= Head;
= current;
= current->next;
