Expert Solution & Answer
Chapter 4, Problem 1RQ
Explanation of Solution
Conditions:
Following are the conditions should be met before an entity is referred as a weak entity:
- The entity should be “existence-dependent” on its parent entity.
- If an entity is referred as an “existence-dependent”, then that entity can exist in the
database if and only if when it is related with another entity existence.
- If an entity is referred as an “existence-dependent”, then that entity can exist in the
- The entity should inherits a section of its primary key (PK) from its parent entity.
Example:
Consider the following ER diagram along with its attributes:
Explanation:
- The entity CLASS is “existence-dependent” on COURSE entity. Hence the CLASS entity uses a PK component from its parent entity (COURSE).
- The CLASS entity’s PK is (COURSE_ID, CLASS_SEC).
- In this strong implementation, the CLASS entity is referred as a weak entity between COURSE and CLASS.

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…

- Don't use ai to answer I will report you answerarrow_forwardYou 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. Your printing result must follow the example output: name: Coco, breed: Domestic short-haired, age: 3 Meow Meowarrow_forwardautomata theory can please wright the exact language it know for example say it knows strings start 0 and end with 1 this is as example also as regular expressionarrow_forward
