Normalization:
The process used to minimize data redundancy and dependency in a relational
- The database table is divided into two or more tables and defines the relationship between those tables.
- If the modifications, deletion or updates occur in one table, the other tables in database get updated by just propagating it.
- In a relational database, the tables with no redundant data and less null values are considered as efficient table.
- This is because, having redundant data and more null values increases the storage space and wastage of memory is imminent.
- Null values cause a problem for data integrity and produces more error in the database.
- If the wasted storage space and null values which cause data integrity hazards are minimized, a highly optimized relational database can be designed.
- The project team should consider using normalization when designing the database, which is the best source to optimize data storage efficiently; this is because, it reduces the data storage space and provides data integrity.
- There are three types of normal forms.
- First normal form (1NF)
- Second normal form (2NF)
- Third normal form (3NF)

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
