Write a MIPS Assembly program that computes the sum of all the odd numbers from 1 ..99 and print out the answer.

IN JAVA LANGUAGE!!!

These questions involve choosing the right abstraction (Collection, Set, List, Queue, Deque, SortedSet, Map, or SortedMap) to efficiently accomplish the task at hand. The best way to do these is to read the question and then think about what type of Collection is best to use to solve it. There are only a few lines of code you need to write to solve each of them. Unless specified otherwise, sorted order refers to the natural sorted order on Strings, as defined by String.compareTo(s). Part 0 in the assignment is an example specification and solution.

Q1)  Read the input one line at a time and output only the last 9999 lines in the order they appear. If there are fewer than 9999 lines, output them all. For full marks, your code should be fast and should never store more than 9999 lines.

Q2) ] Read the input one line at a time and output the current line if and only if you have already read at least 1000 lines greater than the current line and at least 1000 lines less than the current line. (Again, greater than and less than are with respect to the ordering defined by String.compareTo().)

Write a program in C++ called RollDice.cpp that simulates rolling a pair of dice until the total on the dice comes up to be a given number. Ask the user for the number that you are rolling for.

To have your program roll two dice, use the rand() function this way:

die1 = rand() % 6 + 1;
die2 = rand() % 6 + 1;

Your program then computes and prints the number of rolls it takes to get the given number. Valid numbers are 2 through 12.

If the user asked for a 2 your program should output:

It took 20 rolls to get a 2.

(your number of rolls will be different of course)

Although clumsy, the if statements and if-else statements can be used to achieve the same effects as if-elif-else statements. Rewrite the speed3 function：

def speed3():

   kph=float(input('What is the speed in kph?'))

   mph=0.621371*kph

print('The speed is',mph,'mph.')

if mph>80:

   print('You are WAY over the speed limit. Your fine is $200!')

elif 65<mph<=80:

print('You are over the speed limit (65mph) . Slow down1').

elif 30<=mph<=65:

print('You are within the speed limit. Good job!')

else:

  print('You are too slow. Exit highway and use local roads!')

(a) use only if statement

(b) use only if-else statement

Assignment 2 - Employee Hierarchy

In Chapter 9, we created the CommissionEmployee-BasePlusCommissionEmployee inheritance hierarchy to model the relationship between two types of employees and how to calculate the earnings for each. Another way to look at the problem is that CommissionEmployees and BasePlusCommissionEmployees are each Employees and that each has a different CompensationModel object.

A CompensationModel would provide an earnings method. Classes or subclasses of CompensationModel would contain the details of a particular Employee's compensation:

• CommissionCompensationModel - For Employees who are paid by commission, the CommissionCompensationModel class would contain grossSales and commissionRate instance variables, and would define an earnings method to return grossSales * commissionRate.
• BasePlusCommissionCompensationModel - For Employees who are paid a base salary and commission, this subclass of CommissionCompensationModel would contain an instance variable of baseSalary and would define the earnings method to return super.earnings() + baseSalary.

Each of these classes would contain a toString() method that displays the Compensation Model information as illustrated in the sample output.

This approach is more flexible than our original hierarchy. For example, consider an Employee who gets promoted. With the approach described here, you can simply change that Employee's CompensationModel by assigning the composed CompensationModel reference an appropriate subclass object. With the CommissionEmployee - BasePlusCommissionEmployee hierarchy, you'd need to change the Employee's type by creating a new object of the appropriate class and moving data from the old object to the new one.

Implement the Employee class and CompensationModel hierarchy discussed in this exercise. In addition to the firstName, lastName, socialSecurityNumber and CommisionCompensationModel instance variables, class Employee should provide:

• A constructor that receives three Strings and a CommissionCompensationModel to initialize the instance variables.
• A set method that allows the client code to change an Employee's CompensationModel.
• An earnings method that calls the CompensationModel's earning method and returns the result.
• A toString() method that displays all the information about the Employee as illustrated in the sample output.

Your code in the subclasses should call methods in the super classes whenever possible to reduce the amount of code in the subclasses and utilize the code already developed in the super classes as in the code demonstrated in Figures 9.10 and 9.11 in the book.

Use the following code in your main function to test your classes, just copy and paste it into your main method:

        // Create the two employees with their compensation models.
       
        CommissionCompensationModel commissionModel = new CommissionCompensationModel(2000.00, 0.04);
        BasePlusCommissionCompensationModel basePlusCommissionModel = new BasePlusCommissionCompensationModel(2000.00, 0.05, 600.00);
       
        Employee employee1 = new Employee("John", "Smith", "111-11-1111", commissionModel);
        Employee employee2 = new Employee("Sue", "Jones", "222-22-2222", basePlusCommissionModel);
       
        System.out.printf("%s%n%s%n", employee1, employee2);
        System.out.printf("%s%s%s%s%s%8.2f%n%n", "Earnings for ", employee1.getFirstName(), " ", employee1.getLastName(), ": ", employee1.earnings());
       
        // Change the compensation model for the two employees.
       
        CommissionCompensationModel commissionModelNew = new CommissionCompensationModel(5000.00, 0.04);
        BasePlusCommissionCompensationModel basePlusCommissionModelNew = new BasePlusCommissionCompensationModel(4000.00, 0.05, 800.00);
       
        // Set the new compensation models for the employees.
        employee1.setCompensation(basePlusCommissionModelNew);
        employee2.setCompensation(commissionModelNew);
       
        // Print out the new information for the two employees.
        System.out.printf("%s%n%s%n", employee1, employee2);

The output from your program should look like the following:

Commission Rate of: 0.04

Write a python program that implements a Brute Force attack on Shift Cipher. In this program there is only one input - ciphertext - is a sequence of UPPER CASE letters. To make it easy, the program will be interactive and will output all possible plaintexts and ask user which plaintext makes sense. As soon as user will decide YES, the program will stop searching and print the desired plaintext and the found SHIFT KEY.
