Chapter 18, Problem 7RQE
Program Plan Intro
Linked list:
Linked list is a linear and dynamic data structure which is used to organize data; it contains sequence of elements which are connected together in memory to form a chain. The every element of linked list is called as a node.
Adding nodes into linked list:
A new node can be added into a linked list in three ways:
- Insert a node at beginning of the list.
- Insert a node at middle of the list.
- Append a node at end of the list.

Study the code below:
public __________ ____________()
{
MyLinkedList newlist = new MyLinkedList<>();
for(Node ptr=head;ptr!=null;ptr=ptr.next)
{
newlist.prepend(ptr.element);
}
return newlist;
}
What is the purpose of the code
What happens when a programmer attempts to access a node's data fields when the node variable refers to None? How do you guard against it?
*PYTHON
Complete the code provided below, so that it :
Accepts strings from the user till the user enters "End!", and creates a BST from them with respect to the order of their entry
if the user enters "End!" as the first input, then it should:
Display "BST needs at least one node, enter a valid input please!"
Accepts strings from the user till the user enters "End!"
Next, it should display "which node would you pick?", and accept a string (i.e. the key attribute for this Node) from user as an input.
Then, display the distance between the given node from the root of the BST.
The distance between root and a node can be calculated by the number of edges between them
If the string (ie node) is not found then:
Your code should display "Not Found!"
Then, your code should display: ' Would you like to choose another node? Y/N'
If the user enters 'N' end the program, otherwise let the user choose another node and display the distance for the new node.
The program should continue…
