Explanation of Solution
Pros and cons of developments by internet:
Internet has made it easier for people to work together in novel ways and popularized the concept of working at home by connecting the computers and smartphones with internet.
Internet develops many activities in daily life. There are pros and cons of these developments which can be shown below:
Pros:
- Internet develops the concept of working at home and it made work easier to do at any time.
- The concept of working from home replaces the face to face activities, so it will not be time consuming and reduces the time spent in travelling.
- This concept made easier for people to spend their time with family and friends.
Cons:
- The important disadvantage of the concept of working at home is degradation of social skills.
- In case of any disease or illness, employees are not being paid.
- Employees can be frustrated while working alone at home.
Effect on the consumption of natural resources:
“Yes”, it affects the consumption of natural resources.
Reason:
The concept of working at home by connecting computers and smartphones to the internet has made easier for people to save their time which they spent in travelling. Natural resources such as fuel will be reduced with reduce in transportation. This concept also saves electricity because there is no need of work place and parking area.
Effect on the families:
“Yes”, it strengthens families...

Solving Sudoku using Grover's Algorithm
We will now solve a simple problem using Grover's algorithm, for which we do not necessarily know the solution beforehand. 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.
Turning the Problem into a Circuit
We want to create an oracle that will help us solve this problem, and we will start by creating a circuit that identifies a correct solution, we simply need to create a classical function on a quantum circuit

8. Cash RegisterThis exercise assumes you have created the RetailItem class for Programming Exercise 5. Create a CashRegister class that can be used with the RetailItem class. The CashRegister class should be able to internally keep a list of RetailItem objects. 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. When the user is ready to check out, the…
