DSA 03c Linked List Quiz

What is a linked list?

• A data structure that uses hash tables for storage

• A data structure that requires fixed size memory allocation

• A linear data structure where elements are connected via pointers

• A linear data structure with contiguous memory allocation

How are nodes connected in a linked list?

• Via hash functions

• Via stacks

• Via pointers

• Via arrays

What does the last node in a linked list point to?

• The first node

• Null

• The largest node

• A random node

How is memory allocated for nodes in a linked list?

• Using new in C

• Using hash tables

• Using malloc in C++

• Using arrays

What operation is used to insert a new node at the beginning of a linked list?

• Traversal

• Insert

• Search

• Delete

Which operation is used to delete a node from the middle or end of a linked list?

• Insertion

• Traversal

• Deletion

• Reversing

What is the purpose of the reverse method in a linked list?

• To delete all nodes

• To insert new nodes

• To search for a specific node

• To reverse the order of nodes

What is the advantage of contiguous storage over linked storage?

• Requires extra memory for pointers

• Efficient for direct access

• Flexible for dynamic growth

• Allows for circular linked lists

What is the purpose of the Node class in Python code for linked lists?

• To perform mathematical operations

• To handle user input

• To define the linked list structure

• To create graphical interfaces

What is the role of the LinkedList class in Python code for linked lists?

• To store data values

• To manage memory allocation

• To define individual nodes

• To provide methods for operations
