Modify a data structure : Remove Tail

The video tutorial explains how to implement a 'remove tail' function for a linked list. It covers handling both empty and non-empty lists, updating pointers, and testing the function. The tutorial concludes with a successful test and hints at the next topic: searching the linked list.

What is the first step when implementing the remove tail function for a linked list?

• Check if the list is empty

• Update the head pointer

• Add a new node

• Reverse the list

When removing the tail node from a non-empty linked list, what should the tail pointer be updated to?

• The node before the current tail

• A new node

• The node after the current tail

• The head node

What should be done if the list becomes empty after removing the tail node?

• Add a new tail node

• Reverse the list

• Set the head to null

• Set the tail to the head

In the testing phase, what data type is used to demonstrate adding nodes to the linked list?

• Integer

• String

• Boolean

• Float

What is the expected output when the remove tail function is tested with nodes added to the head?

• An error message

• The first node added

• The last node added

• A null value
