What are the basic components of a linked list?
Head and tail are the only important components
Data members for the information to be stored and a link to the next item
Generic class because without this linked list is not possible
None of the above
What is the time complexity to count the number of elements in the linked list?
O(1)
O(n)
O(logn)
None of the mentioned
What is the output of following fun
1->2->3->4->5->6
void fun(node* start)
{
if(start == NULL)
return;
cout<<start->data;
if(start->next != NULL )
fun(start->next->next);
cout<<start->data;
}
1 4 6 6 4 1
1 3 5 1 3 5
1 2 3 5
1 3 5 5 3 1
In addition to the info and link components, the linked list must also contain what other components?
Sorting information about the list
Head and tail pointers to the first and last nodes
The current node that was last accessed
All of the above
What is the proper code for accessing the information of the second item in a linked list?
Head->info
Head->link->info
Head->link->link->info
None of the above
Giving the fixed size of an array is not important. Which class is more efficient at storing and retrieving information?
A linked list because of the nodes
An array because of the reduced code and efficient storage allocation
Neither is more efficient than the other
None of the above
void fun1(node* head) {
if(head == NULL)
return;
fun1(head->next);
cout<< head->data;
}
Prints all nodes of linked lists
Prints all nodes of linked list in reverse order
Prints alternate nodes of Linked List
Prints alternate nodes in reverse order
Which of the following code fragments properly insert 50 into the linked list at the position after node p?

C) newNopde = new Node(); newNode.info = 50; newNode.link = p.link; p.link = newNode;
Code A
Code B
Code C
Code B and C
Which of the following code fragments properly delete the item at node p?
A) p.link = null;
B) q = p.link; p.link = q.link; q = null;
C) q = p.link; p.link = q.link;
Code A
Code B
Code C
Code A and C
Which of the following operations is performed more efficiently by doubly linked list than by singly linked list?
Deleting a node whose location in given
Searching of an unsorted list for a given item
Inverting a node after the node with given location
Traversing a list to process each node
