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 that…arrow_forwardusing r languagearrow_forward
- 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.

You are tasked with creating a Java record of Dog (UML is shown below). The dog record should include the dog's name, breed, age, and weight. You are required to implement the Comparable interface for the Dog record so that you can sort the records based on the dogs' ages. Create a Java record named Dog.java. name: String breed: String age: int weight: double + toString(): String > Dog + compareTo(otherDog: Dog): int > Comparable 2. In the Dog record, establish a main method and proceed to generate an array named dogList containing three Dog objects, each with the following attributes: Dog1: name: "Buddy", breed: "Labrador Retriever", age: 5, weight: 25.5 Dog2: name: "Max", breed: "Golden Retriever", age: 3, weight: 30 Dog3: name: "Charlie", breed: "German Shepherd", age: 2, weight: 22 3.

- In a network, information about how to reach other IP networks or hosts is stored in a device's routing table. Each entry in the routing table provides a specific path to a destination, enabling the router to forward data efficiently across the network. The routing table contains key parameters determining the available routes and how traffic is directed toward its destination. Briefly explain the main parameters that define a routing entry.arrow_forwardYou are troubleshooting a network issue where an employee's computer cannot connect to the corporate network. The computer is connected to the network via an Ethernet cable that runs to a switch. Suspecting a possible layer 1 or layer 2 problem, you decide to check the LED status indicators on both the computer's NIC and the corresponding port on the switch. Describe five LED link states and discuss what each indicates to you as a network technician.arrow_forwardYou are a network expert tasked with upgrading the network infrastructure for a growing company expanding its operations across multiple floors. The new network setup needs to support increased traffic and future scalability and provide flexibility for network management. The company is looking to implement Ethernet switches to connect various devices, including workstations, printers, and IP cameras. As part of your task, you must select the appropriate types of Ethernet switches to meet the company's needs. Evaluate the general Ethernet switch categories you would consider for this project, including their features and how they differ.arrow_forward
