Explanation of Solution
SQL DELETE statement:
- The “DELETE” statement would delete one or multiple rows in a table.
- The criteria for deleting values should be provided in “WHERE” clause.
- The syntax for “DELETE” statement is shown below:
DELETE FROM TableName WHERE Criteria
- Here, “TableName” denotes name of table and “Criteria” denotes an expression conditional.
- It deletes rows from table that would satisfy the “Criteria”...

Task 2: Comparable Interface and Record (10 Points)
1. 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. Print the dogs in dogList before sorting the dogList by age. (Please check the example
output for the format).

The OSI (Open Systems Interconnection) model is a conceptual framework that standardises the functions of a telecommunication or computing system into seven distinct layers, facilitating communication and interoperability between diverse network protocols and technologies. Discuss the OSI model's physical layer specifications when designing the physical network infrastructure for a new office.
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.

- 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…arrow_forwardI need help to solve a simple problem using Grover’s algorithm, where the solution is not necessarily known beforehand.
