Write a function matchSuit() that simulates repeatedly drawing a pair of playing cards from a shuffled deck (of 52 cards) until the pair of cards share the same suit (or you run out of cards). The function should return the total number of cards drawn. Use a while loop. To draw each card, call the drawCard function you wrote above.

1. Implementing a cryptosystem:

Choose one of the following cryptography techniques and implement it using any programming language you prefer. Your program should provide the user with two options Encryption and Decryption, with a simple UI to get the input from the user, and view the result. You can use any restriction you need for the user input but you need to clarify that and validate the user input base on your restriction.

● Feistel

● Keyword columnar

● Any cryptosystem of your choice (needs to be approved by the instructor)

Notes:

• Submission materials:
  • Your source code
  • Report containing Description of your cryptosystem, the encryption and decryption processes, screenshots of all the execution results.
• Make sure your code is defensive code against any programming flaws.
• Test your program with different input.
• You must reference your work if you used any external sources for the code or report.

There is a Java program that is missing one recursive function:

public class GCD {

/* There is a neat trick with recursive programming. The function described

   * below requires that y is at most x. Rather than add this to the recursive

   * function definition, we can add a front-end, helper function.

   *

   * I wrote this function for you and I called it gcd. The recursive logic goes

   * in a function called gcd_rec. All gcd does is make sure that x is not

   * smaller than y.    

   */

/* Requires x >= y

   *            / x            when y is 0

   * gcd(x,y) = |

   *            \ gcd(y, x%y) otherwise

   */

public static int gcd_rec(int x, int y) {

    return 0;

}

public static int gcd(int x, int y) {

    if(x < y)

      return gcd_rec(y,x);

    else

      return gcd_rec(x,y);

}

/* Greatest Common Divisor Test Framework

   */

public static void main(String[] args) {

    int[] inputX = {10, 35, 14, 4181};

    int[] inputY = { 8, 15, 35, 6765};

    int[] expect = { 2, 5, 7,    1};

    boolean error = false;

    assert(inputY.length == inputX.length);

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

      int answer = gcd(inputX[i], inputY[i]);

      if(answer != expect[i]) {

        System.out.printf("ERROR: gcd(%d,%d) returned %d not %d.\n",

                          inputX[i], inputY[i], answer, expect[i]);

        error = true;

      }

    }

    if(error)

      System.exit(1);

    else

      System.out.println("Good Job!");

}

}

• Write a convertToMetric class that has the following field:
  • standard - holds a double, standard length value in feet.
• The class should have the following methods:
  • Constructor - that accepts a length in feet (as a double) and stores it in the standard field.
  • setStandard - accepts a standard length in feet and stores it in standard.
  • getStandard - returns the value of the standard field, as a length in feet, no conversion required.
  • getMeters - returns the value of the standard field converted to meters.
  • getCentimeters - returns the value of the standard field converted to centimeters
• A second class will be created and used to test the new object class. This, executable class, is to instantiate an object of 'convertToMetric' type. Then it will allow the user to use keyboard input to input a value for standard. That value will then be converted to meters and centimeters, and displayed.
• Make sure that your output (or display) is user-friendly or easy to read and understand. You should display the length in feet, length in meters and length in centimeters.

Part 1 - Java program named MemoryCalculator

In your Ubuntu VM (virtual machine), using terminal mode ONLY, do the following:

Create the folder program2

Each record in this file represents the possible location of an error found in RAM. (Hint: One of them is not on one of the chips.)

Assume you have a computer with 4 gigs of RAM, each gig in a different memory chip, therefore you have 4 one gig RAM chips.

---------decimal---------------

HINT:

RAM chip 0 contain addresses: 0 - 8,589,934,584 bits

RAM chip 1 contain addresses: 8,589,934,585 - 17,179,869,184 bits

RAM chip 2 contain addresses: 17,179,869,185 - 25,769,803,768 bits

RAM chip 3 contain addresses: 25,769,803,769 - 34,359,738,368 bits

HINT:

RAM chip 0 contain addresses: 0 - 1,073,741,823 bytes

RAM chip 1 contain addresses: 1,073,741,824 - 2,147,483,648 bytes

RAM chip 2 contain addresses: 2,147,483,647 - 3,221,225,471 bytes

RAM chip 3 contain addresses: 3,221,225,472 - 4,294,967,296 bytes

In the same folder, in terminal mode using an editor, create a Java program to do the following:

- Call the Java program – MemoryCalculator.java

- Open the RAMerrors file

- Read each record

- Print the RAM memory chip where the error is located for each record

*** CREATE YOUR OWN METHODS THAT WILL CONVERT

HEX TO BINARY AND BINARY TO DECIMAL

*** DO NOT USE JAVA'S AUTOMATIC CONVERSION METHODS

Part 2 - Linux Shell Scripting

- Create a sh file named: program2.sh

- Set the permissions for this this *.sh file using this command to make it executable: chmod 755 program2.sh

- program2.sh should add your name and the current date and time to a NEW file called results.txt -program2.sh should then do the following:

How: - Ask the user to enter a number.

- Verify that the number is between 1 and 50, inclusive.

- If the number is not between 1 and 50, then keep asking the user to enter a number until it is valid.

- Use a loop from 1 to the value entered by the user

- Sum the results of all the included numbers, but do not include any output yet.

- After the loop ends, display the sum and append it to the results.txt file on a new line as follows

Sum of numbers is xxx

The results.txt file should have 3 lines in it when done.

Using a vending machine requires instructions from the person buying an item and the machine dispensing the item. Using terms and concepts learned this week, discuss the following activities.

What actions by either the person buying an item or the vending machine would you describe as a privilege or non-privileged instructions? Why?

Relate memory management concepts (virtual, real) to the operation of the vending machine. Relate processes and threads to the operation of the vending machine.

Directly address each question in your post. Your initial (first) post must be at least 150 - 200 words long.

What is a software process model? Explain. Describe completely any two generic software process models with relevant diagrams using any two different examples of software applications (one for each model).

2. Draw a state-machine model (diagram) for the control software for the camera on your mobile phone. You can ignore the flash component.

3. Draw a sequence diagram for a student to register for a course for the Spring 2021 semester. Check academic and financial holds, pre-requisites and ensure that the catalog of courses is available for the student to check the CRN and name of the course and section.

4. Which software attributes are most critical for the following systems? Explain your reasoning for each attribute in detail. a. Software used to control a robotic arm to fill in prescriptions at a large pharmacy. b. Application similar to Mercy Connect, which you can use to register for courses, apply for and check financial aid, review transcripts, etc.

5. Create a complete list of software requirements (user, system, functional, non-functional) for a typical Metro North or Amtrak Ticket Machine system. If you are not familiar with Metro North or Amtrak, pick any train station Ticket Machine in your city.
