Question
Chapter 7.8, Problem 19CP
Program Plan Intro
Two-dimensional list:
- • A list that has another list as its elements is called as two-dimensional list.
- • Two-dimensional list is a type of nested list, where elements are arranged in row and column order.
- • The element in the list is retrieved using two subscripts. One subscript specifies the row and the other subscript specifies the column.
- • The two-dimensional lists are helpful in processing various sets of information.
Syntax:
In Python, two-dimensional lists have the below format:
List_name = [list1,list2, …, listn]
Explanation:
Here,
- • The variable “List_name” is a two-dimensional list.
- • The variables “list1”, “list2”, and “listn” are elements of two-dimensional list “List_name” that indicates one-dimensional lists.
Example:
Consider the following example that shows a two-dimensional list.
student_scores = [[45, 63, 72], [81, 58, 97], [100, 23, 67]]
Explanation:
In the given above code,
- • The variable “student_scores” is a two-dimensional list that stores the students’ scores at various exams.

If a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A. Like all ICMP messages, this is addressed to A as a whole, not to port P on A.
(a) Give an example of when an application might want to receive such ICMP messages.
(b) Find out what an application has to do, on the operating system of your choice, to receive such messages.
(c) Why might it not be a good idea to send such messages directly back to the originating port P on A?

Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm.

The class should have the following methods: A method named purchase_item that accepts a RetailItem object as an argument. Each time the purchase_item method is called, the RetailItem object that is passed as an argument should be added to the list. A method named get_total that returns the total price of all the RetailItem objects stored in the CashRegister object’s internal list. A method named show_items that displays data about the RetailItem objects stored in the CashRegister object’s internal list. A method named clear that should clear the CashRegister object’s internal list. Demonstrate the CashRegister class in a program that allows the user to select several items for purchase.
