Given a circular linked list in which the last node is connected to the first node. If we set a node curr equal to first node at the start of traversal and we start traversing the circular linked list, the condition to check if we have reached the end of the list then becomes ) curr = first ) curr.next == null ) curr.next.next == first ) curr.next == first ) None of the Above

Question 1 The code below defines a singly-linked list. This consists of the following definition of node: 1 struct node { int val; struct node * next; 4 } Also, it uses the following insert function: struct node * insert(struct node * first, const int val) { 6 struct node * pred = NULL, * succ = first; 7 while (succ != NULL) { 8 if (succ->val val > val) 10 11 break; 12 succ = succ->next; 13 } struct node * this = malloc(sizeof (struct node)); this->val = val; 14 15 16 this->next = succ; 17 if (pred != NULL) { pred->next return first; } else { 18 this; %3D 19 20 21 return this; 22 } 23 } Note that the code above compiles correctly. (a) Give an implementation in C for a function that prints all values in the singly-linked starting from the first node and following the next node one by one along the list. Use the following signature: void print (struct node * first);

When removing curNode from a doubly-linked list with at least 2 elements, the list's tail may be assigned with Group of answer choices curNode curNode's predecessor curNode's successor null

Given the following C code: atruct Node int data: struct Node previ struct Node next: Which of the following statements deletes the node pointed by X? Assume that X points to the first node of linked list and head points to the head of linked list. a) X->prev-x->next; X->next-X->prev; b) Head-X->next; Head >prev-NULL; c) Head-X->prev; X->next-NULL; d) X->prev->prev - X->prev; X->next->next-X->next;
