Modify a data structure : Add To Tail

The video tutorial explains the 'add to tail' method for a linked list, which is the reverse of the 'add to head' method. It covers creating a new node, handling scenarios where the linked list is empty, and finalizing the method by setting the new node as the tail. The tutorial concludes with a plan to test the method in the next video.

What is the primary difference between the 'add to tail' and 'add to head' methods?

• The 'add to tail' method removes a node from the list.

• The 'add to tail' method does not require a value parameter.

• The 'add to tail' method is the reverse of the 'add to head' method.

• The 'add to tail' method adds a node at the beginning of the list.

When adding a node to a non-empty list, what is the next step after creating the new node?

• Ignore the current tail node.

• Set the head pointer to the new node.

• Set the next pointer of the current tail to the new node.

• Remove the current tail node.

In the 'add to tail' method, what happens if the linked list is empty?

• The new node becomes both the head and the tail.

• The new node is discarded.

• The list remains empty.

• The new node is added to the middle of the list.

What is the final step in the 'add to tail' method?

• Set the head pointer to null.

• Set the tail of the linked list to the new node.

• Remove the head node.

• Add another node to the head.

Why is it important to check if the linked list is empty before adding a new node?

• To ensure the new node is added to the correct position.

• To avoid adding duplicate nodes.

• To remove all existing nodes first.

• To change the data type of the list.
