I need to create a servlet that takes in an input that will do the following calculations.

1. If the input number is a prime, just output a message showing that it is a prime;
2. If the input number is not a prime and it is an odd integer, write it as a product of two smaller odd integers;
3. If the input number is not a prime and it is an even integer, first extract the largest power of 2, then for the remaining odd number, try to factorize it if you can. For your output, you give the power of 2 as one number and one more factor if this factor is a prime, or two more factors if you can still factorize the odd number after extracting the power of 2.

When you buy a new computer what would you do to harden it

Provide two classification scenarios where you can use classification tree models but not logistic regression models. For each problem, identify a target variable and four possible predictor variables.

Part II: Programming Questions

NOTE: CODING LANGUAGE IS C#

PQ1. How would you declare the following scalar and non-scalar (vector) variables?

1. counter, an integer
2. sum, a decimal number
3. average, a decimal number
4. grades, an array of 32 decimal numbers

PQ2.

1. How would you initialize the array above with numbers between 0.0 and 4.0 representing the grades of all courses a senior has received in the four years of college?
2. Instead of initializing the array above, how would you, in a loop, accept input from the user for the 32 grades?

PQ3.

1. How would you calculate the sum of all the grades in the array above?
2. How would you average the sum above?

PQ4. The algorithm for checking if a number is a prime is to check if it is divisible by any number less than itself other than 1. (Divisibility implies that if you use the modulus operator, %, the result will be 0). Write a function to check if a number is a prime.

Write a C program to implement Jacobi iterative method for sovling a system of linear equations. Use the skeleton code.

1. Create a base class called Vehicle that has the manufacturer’s name (type String), number of cylinders in the engine (type int). Then create a class called Truck that is derived from Vehicle and has additional properties: the load capacity in tons (type double) and towing capacity in tons (type double).

Add the following methods to the Vehicle class:

1. A default constructor that sets the vehicle class properties to default values (manufacturer = "None"; cylinders = 0).
2. A constructor that sets a vehicle properties (manufacturer and cylinders) to a specified values.
3. The accessor and mutator methods for manufacturer and cylinders.
4. A method called writeOutput that prints out a vehicle object information (manufacturer and cylinders).
5. A method named equals to test whether two instances of vehicle objects are equal. The method returns Boolean data type.

Add the following methods to the Truck class:

1. A default constructor that sets the truck class properties to default values (load capacity = 0; towing capacity = 0).
2. A constructor that sets a truck properties (manufacturer, cylinders, load capacity, and towing capacity) to a specified values.
3. The accessor and mutator methods for load capacity, and towing capacity.
4. A method called writeOutput that overrides the writeOutput from Vehicle. This new version needs to prints out a truck object information (manufacturer, cylinders, load capacity, and towing capacity).
5. A method named equals to test whether two instances of truck objects are equal. The method returns Boolean data type.

Write a driver program that tests all your methods. Create at least two objects of truck class, and two objects of vehicle class.

Write a simple lottery program which can do the following:

1. asks the user to provide an integer value from 1 to 5

2. generates one random integer number from 1 to 5

3. display “You lost $1” if the two numbers are different, and display “You won $5” otherwise.the program asks if the user wants to continue playing the lottery.

If yes, the program repeats steps 1-3. If no, the program terminates.

Consider the following code:

values = [2, 5, 8, 12, 15]
values2 = {v % 3 for v in values}

What will be the length of values2?

Consider the following code:

values = ["moose", "giraffe", "antelope", "tortoise", "chinchilla"]
values2 = [len(s) for s in values if "a" in s]

What will be the value of values2[1]?

Consider the following code:

numbers = [1, 2, 7, 9, 13]
numbers2 = [n // 2 for n in numbers]

What will be the value of numbers2[2]?

Im trying to create a function in C where it takes an array and size and returns the largest absolute value in the array (either negative or positive) using only stdio.h. Any help would be greatly appreciated!

Ex: if the array is { -2.5, -10.1, 5.2, 7.0}, it should return -10.1

Ex: if the array is {5.1, 2.3, 4.9, 1.0}, it should return 5.1.

double getMaxAbsolute(double array[], int size)
{
    double max = array[0];
   double abs[size];
   for (int i = 0; i < size; i++) {
      
        if ( array[i] >= 0){
        abs[i] = array[i];
        }
        else if (abs[i] < 0){
           abs[i] = - array[i];
       }

       if (abs[i] > max)
       {
            max = array[i];
          
        }
   }

   return max;
}

(The Colorable interface) Design an interface named Colorable with a void method named howToColor(). Every class of a colorable object must implement the Colorable interface. Design a class named Square that extends GeometricObjectand implements Colorable. Design another class named Trianglethat extends GeometricObjectand implements Colorable. Implement howToColor inSquareto display the message Color all four sides. ImplementhowToColor inTriangleto display the message Color all three sides.

Draw a UML diagram that involves Colorable, Square, Triangle, and GeometricObject.

Write a test program that creates an array of five GeometricObjects. For each object in the array, display its area and invoke its howToColor method if it is colorable.

{
   public void howToColor();

//A method named toString() that returns a string description for the triangle.

public void howToColor()

class TestGeometricObject

GeometricObject[] f = new GeometricObject[2];
f[0] = new Square(20);
f[1] = new Triangle(6.5, 14.9, 11.3);

for(int i=0;i<f.length;i++)
