Data Structure: Linked List Quiz

Explain the process of inserting a node at the beginning of a linked list.

• Create a new node, set its next pointer to a random node, update head to new node.

• Create a new node, set its next pointer to null, update head to new node.

• Create a new node, set its next pointer to current head, update head to new node.

• Create a new node, set its next pointer to the previous node, update head to new node.

What are some common operations that can be performed on a linked list?

• insertion, deletion, traversal, searching, updating nodes

• reversing

• merging

• sorting

Provide an example of an application where a linked list is used.

• Fitness tracker

• Music playlist

• Calendar app

• Weather forecast app

How is memory managed in a linked list?

• Memory is managed by using a fixed-size array for all nodes

• Memory is managed by storing all nodes in a single block of memory

• Memory is managed by allocating memory only once for the entire linked list

• Memory is managed dynamically by allocating and deallocating memory for each node as needed.

Explain the process of deleting a node from a linked list.

• The process involves finding the previous node, updating its next pointer, and freeing the memory of the node to be deleted.

• Deleting a node requires updating the previous node's data

• The process involves reversing the linked list

• To delete a node, simply disconnect it from the list

What are the advantages of using a linked list over an array?

• Linked lists provide dynamic size, easy insertion and deletion, no need for contiguous memory allocation, and efficient memory usage for small data sizes.

• Linked lists have fixed size

• Linked lists require contiguous memory allocation

• Linked lists are slower than arrays
