What is the structure of a node in a linked list?

• Number and pointer to the previous node

• Data and pointer to the next node

• Pointer to the previous node and pointer to the next node

• Number and pointer to the next node

What is the main advantage of linked lists?

• Efficient memory

• Random access to elements

• Easy reverse traversal

• Need to know the size in advance

How to add an element at the beginning of a linked list?

• Allocate memory for the new node, store data, change pointer to the previous node to head, change head to the previous node

• Allocate memory for the new node, store data, change pointer to the new node to head, change head to the newly created node

• Allocate memory for the new node, store data, change pointer to the next node to head, change head to the newly created node

• Allocate memory for the new node, store data, change pointer to the previous node to head, change head to the newly created node

What is the main purpose of traversing a linked list?

• Displaying the content

• Deleting elements

• Adding elements

• Calculating the size of the list

What does the 'next' pointer represent in a node of a linked list?

• Address of the previous node

• Value of the node's data

• Start indicator of the list

• Address of the next node

What is the basic action to allocate memory and store data for a new node in a linked list?

• Adding elements to the end of the linked list

• Allocating memory and storing data for the new node

• Changing the next of the last node to the newly created node

• Traversing to the last node

What is the necessary action to add a node at the end of a linked list?

• Adding elements at the end of a linked list

• Allocating memory and storing data for the new node

• Change the next of the last node to the newly created node

• Traverse to the last node

What do you need to do to add a node in the middle of a linked list?

• Change the next of the last node to the newly created node

• Adding elements to the middle of the linked list

• Allocate memory and store data for the new node

• Traverse to the last node

What is the basic action to delete elements from a linked list?

• Deleting elements from the linked list

• Change the next of the last node to the newly created node

• Memory allocation and data storage for the new node

• Traverse to the last node

What does the action of traversing to the last node in a linked list represent?

• Change the next of the last node to the newly created node

• Allocate memory and store data for the new node

• Add elements to the end of the linked list

• Traverse to the last node
