In a doubly linked list, what is the time complexity for removing an element from the middle of the list?

• A) O(1)

• B) O(log N)

• C) O(N)

• D) O(N/2)

How can you efficiently insert an element at a specific position in a singly linked list without traversing the list from the beginning?

• A) By using recursion

• B) By using a dummy node

• C) By using a circular linked list

• D) It's not possible without traversal.

What is the primary advantage of using a circular linked list in specific applications?

• A) It allows for efficient random access.

• B) It simplifies element insertion and deletion.

• C) It avoids null pointer checks during traversal.

• D) It uses less memory than other linked list types.

Which of the following data structures can be used to implement a stack efficiently?

• A) Singly linked list

• B) Doubly linked list

• C) Circular linked list

• D) All of the above

What is the purpose of a "header node" in a doubly linked list?

• A) It marks the end of the list.

• B) It contains data like other nodes.

• C) It simplifies traversal and insertion at the beginning.

• D) It's not used in doubly linked lists.

Which of the following operations is most efficient in a singly linked list compared to other linked list types?

• A) Insertion at the beginning

• B) Insertion at the end

• C) Random element access

• D) Deletion of elements

In a circular singly linked list, how can you determine the length of the list efficiently?

• A) Traverse the list from the beginning to the end, counting nodes.

• B) Traverse the list from the end to the beginning, counting nodes.

• C) Use a separate variable to keep track of the length as elements are inserted or removed.

• D) It's not possible to efficiently determine the length of a circular singly linked list.

Which of the following is an advantage of using a linked list over an array?

• A) Constant time access to any element

• B) Efficient memory utilization

• C) Faster search operations

• D) Ability to store elements of different data types

Which of the following is a disadvantage of using a circular linked list?

• A) Difficulty in implementing insertion and deletion operations

• B) Inability to store large amounts of data

• C) Increased memory overhead compared to other types of linked lists

• D) Limited flexibility in traversing the list
