Expert Solution & Answer
Chapter 10, Problem 21RQE
Explanation of Solution
Purpose of “delete” operator:
The purpose of “delete” operator is to clear or free the memory that was allocated using a “new” operator. The allocated memory gets de-allocated when “delete” operator is used.
Example:
//null pointer declaration
int *myptr = nullptr;
//dynamic allocation of memory
myptr = new int;
//free the memory ...

I need help to solve a simple problem using Grover’s algorithm, where the solution is not necessarily known beforehand. The problem is a 2×2 binary sudoku with two rules:
• No column may contain the same value twice.
• No row may contain the same value twice.
Each square in the sudoku is assigned to a variable as follows:
We want to design a quantum circuit that outputs a valid solution to this sudoku. While using Grover’s algorithm for this task is not necessarily practical, the goal is to demonstrate how classical decision problems can be converted into oracles for Grover’s algorithm.
Turning the Problem into a Circuit
To solve this, an oracle needs to be created that helps identify valid solutions. The first step is to construct a classical function within a quantum circuit that checks whether a given state satisfies the sudoku rules.
Since we need to check both columns and rows, there are four conditions to verify:
v0 ≠ v1 # Check top row
v2 ≠ v3 # Check bottom row…

- You can use Eclipse later for program verification after submission. 1. Create an abstract Animal class. Then, create a Cat class. Please implement all the methods and inheritance relations in the UML correctly: Animal name: String # Animal (name: String) + getName(): String + setName(name: String): void + toString(): String + makeSound(): void Cat breed : String age: int + Cat(name: String, breed: String, age: int) + getBreed(): String + getAge (): int + toString(): String + makeSound(): void 2. Create a public CatTest class with a main method. In the main method, create one Cat object and print the object using System.out.println(). Then, test makeSound() method.
