In a language of your own choosing, write a computer program that implements the Restoring Twos Complement Division process. In addition to program source code, provide a screenshot showing the tasks below. Use 8 bits for all registers.

1. Provide an output that shows your input decimal values.

2. Provide an output that shows the initial values in registers A, Q, and M.

3. Demonstrate that your program works in the following cases by showing the output in registers A and Q after the final cycle and the final value in 2s complement for negative numbers:
   1. divide two positive numbers with no remainder
   2. divide two positive numbers with a remainder

1. 1. 3. divide two negative numbers with no remainder

1. 1. 4. divide two negative numbers with a remainder

1. 1. 5. divide a positive number by a negative number with a remainder

1. 1. 6. divide a positive number by a negative number without a remainder

1. 1. 7. divide a negative number by a positive number with a remainder

1. 1. 8. divide a negative number by a positive number without a remainder

4. Show the output of your result in decimal format yRx where y is the integer value and x is the remainder value. e.g. 4R0 would be 4 with a remainder of 0, -4R-2 would be -4 with a remainder of -2.

Problem:

You will write a program to compute some statistics based on monthly average temperatures for a given month in each of the years 1901 to 2016. The data for the average August temperatures in the US has been downloaded from the Climate Change Knowledge Portal, and placed in a file named “tempAugData.txt”, available on the class website. The file contains a sequence of 116 values. The temperatures are in order, so that the first one is for 1901, the second is for 1902, and so on through 2016.

The statistics you should compute in your program are:

• The average of the monthly average temperatures for the entire time period.

• The number of years that the monthly average reached at least X degrees where X is a value input from the user. These years should also be displayed to the screen.

• The maximum monthly average temperature for the time period and in what year it occurred.

• The minimum monthly average temperature for the time period and in what year it occurred.

Input: Your program should ask the user for the name of the file, and then open that file for input. It should then ask the user for a boundary temperature (the X in the second bullet above) that is used to calculate some of the statistics. Processing: Compute the statistics requested above.

Output: Display the statistics, labeled, and with the temperatures formatted to 1 decimal place. Also output the count of the years above X before outputting the list of the years.

Sample output:

Please enter the name of the temperature data file: tempAugData.txt Please enter the boundary temperature: 68.0

Climate Data statistics: Average temperature: 66.2

Years that averaged at least 68.0 degrees: 7 1936 1995 2003 2007 2010 2011 2016

Maximum average temperature: 68.9 occurred in 2007

Minimum average temperature: 63.9 occurred in 1927

Additional Requirements:

• Your program must compile and run, otherwise you will receive a 0.

• Your program should test for file open errors.

• I recommend temporarily echoing the input from the file to the screen (using cout) to be sure you are reading the input correctly into your array.

• You should have many separate loops in your program. Do not try to compute everything in one single loop.

• For partial credit, implement some subset of the features completely. This will probably lead to a better score than implementing every feature poorly

Password Checking
Software to reset passwords often requires the user to enter the password twice, checking to make sure it was entered the same way both times. Write a program in Python that contains functions/methods in it that can verify that the two passwords entered are correct. Your project should contain a method that asks the user to enter a password twice, then either tell the user that the two entries were not the same and then start the process over again. Or, if they are the same, tell the user that the new password was accepted.

Additionally, the user is required to enter a password that meets specific security requirements. Proper Passwords are required to follow these rules:

• The password must be at least 12 characters long.

• The password must contain at least:
  - one alpha character [a-zA-Z];
       - one numeric character [0-9];
       - one character that is not alpha or numeric, such as
                “! @ $ % ^ & * ( ) - _ = + [ ] ; : ' " , < . > / ?” this is an example, all non-alpha or numeric characters should be included.

• The password must not:
  - Contain spaces;
      - Or, begin with a non-alpha-numeric character;
• Finally, the password cannot contain repeating character strings of 2 or more identical characters, such as “11” or “aa”.

Your task is to create a project to verify whether or not a prospective proper password meets these requirements and that the user has entered the correct password in twice. Hint, a modular solution to this assignment will be the most efficient approach to meeting the requirements of this project

The project should identify to the user the types of rule violations that are contained in an improperly entered password

The project should use a modular solution using user-defined functions

Q1: Server Design Models: (explain clearly) a. For a multi-threaded server, describe the advantages of adopting the many-to-one threading model. b. For a multi-threaded server, describe the advantages of adopting the one-to-one threading model.

Write a C++ code that keeps reading integer numbers (x) until a negative number is entered. Every time x is entered, the program does the following: calculates and prints the product of odd numbers. calculates and prints the count of numbers that ends with 19. Example, 19, 3219, 50619,....etc calculates and prints the percentage of the numbers that contain 3 digits exactly, such as, 301, 500, 206,...etc.

1. Write a queue client, "LineNum," that takes an integer command line argument “n” and prints the nth string from the first string found on standard input. [MO6.2]

Please note that you would need to use a queue to implement it for full credit. You should add the strings inputted by the user to a queue using the enqueue method. Then you should remove and return "n" strings from the queue using the dequeue method. The nth string that is returned by the dequeue method should then be printed out.

• Sample runs would be as follows.
  
  >java LineNum 2
  apple
  save
  that
  is
  too
  me
  <CTRL-D>
  2 from the first is save
  
  >java LineNum 3
  this
  is
  not
  a
  shorter
  version
  <CTRL-D>
  3 from the first is not

This is the code I have, but i keep getting errors.

public class LineNum { // public class LineNum
public static void main(String[] args) { // main method
int n = Integer.parseInt(args[0]); // variable n parses integers from args
Queue<String> queue = new Queue<String>(); // new String queue
//LinkedList<java.lang.String> Dequeue = new LinkedList();
while (!StdIn.isEmpty()) { // while standard input is empty
String item = StdIn.readString();
// String item read string from standard input
if (!item.equals("-")) // if item equal - then ebqueue item
queue.enqueue(item);
else if (!queue.isEmpty()) // otherwise if queue is empty
StdOut.println(queue.dequeue() + " "); // print dequeue + a space
}
  
StdOut.println(queue);
for (int i = 1; i < n; i++) // for loop i=1, <n, increments i
queue.dequeue(); // dequeues element on each loop until i = n
// StdOut.print(queue.size() + " left on queue)");
// StdOut.println("The dequeue contains: " +queue.dequeue() + " ");
StdOut.println(n+ " from the first is " +queue.dequeue());
// Prints number from first and current element in dequeue
  
}
}
these are the errors i'm getting:
