Create a list : Implement List Insert

The video tutorial explains how to build, insert, and remove nodes in a linked list. It covers creating a linked list from scratch, inserting nodes at the beginning and end, and removing nodes efficiently. The tutorial emphasizes the power of linked lists in terms of insertion and removal operations, highlighting their efficiency.

What is the initial step in creating a linked list?

• Reversing the list

• Removing a node

• Initializing an empty list

• Adding a node at the end

How can you build a linked list in reverse order?

• By adding nodes at the end

• By removing nodes from the front

• By reversing the entire list

• By adding nodes at the front

What is crucial to remember when inserting a node at the beginning of a list?

• To update the last node

• To reverse the list

• To maintain reference to the existing list

• To remove the first node

What happens if you lose reference to the existing list when inserting a node at the beginning?

• The list becomes reversed

• The list remains unchanged

• The existing nodes are lost

• A new list is created

How can you ensure a node is correctly inserted at the beginning of a list?

• By maintaining the reference to the existing list

• By removing the first node

• By reversing the list

• By updating the last node

What is the first step in appending a node to the end of a linked list?

• Initialize a new list

• Remove the last node

• Reverse the list

• Find the last node

What is the result of appending a node to the end of a linked list?

• The first node is removed

• The node becomes the new last node

• The list remains unchanged

• The list is reversed

How do you remove a node from the middle of a linked list?

• By updating the previous node's pointer

• By reversing the list

• By adding a new node

• By initializing a new list

What is the advantage of using a linked list for removal operations?

• It requires reversing the list

• It is time-consuming

• It requires additional memory

• It has a constant time complexity

What is the role of a current pointer in a linked list?

• To reverse the list

• To maintain the list order

• To facilitate node removal

• To add nodes at the end
