Why must you keep the back-up copy of your keyring files in a safe place?

Given the following attributes in a project management:

• Project scope & feasibility
• Documentation
• Project planning
• Testing and piloting
• Risk minimisation

Discuss in detail each of them and on how would you use them as the IT manager for the company. Provide a details information support your discussion.

Use MIPS write an assembly program which asks the user to enter 3 number. The program
then sorts these numbers, the prints them from largest to smallest.

The answer should be in JAVA.

You will design and implement two classes to support a client program, RockPaperScissorsGame.java, to simulate Rock-Paper-Scissors game.

Read and understand the client program to find out the requirements for the HandShape and Player classes.

The rules of the Rock-Paper-Scissors game are:

    Scissors✌️ beats Paper✋ that beats Rock✊ that beats Scissors✌️

Additionally, to simplify the game logic (and complexify a little bit the HandSahpe class) , two players cannot show the same hand shape.

The followings are some sample runs:

$java RockPaperScissorsGame
Alice shows Paper
Bob shows Scissors
Bob wins!

$java RockPaperScissorsGame
Alice shows Paper
Bob shows Rock
Alice wins!

$java RockPaperScissorsGame
Alice shows Scissors
Bob shows Rock
Bob wins!

RockPaperScissorsGame.java

public class RockPaperScissorsGame {

        public static void main(String[] args) {
                
                String[] handShapeName = {"Rock", "Paper", "Scissors"};
                
                HandShape handShape = new HandShape();
                
                Player player1 = new Player("Alice");
                Player player2 = new Player("Bob");

                System.out.println(player1.getName() + " shows " + handShapeName[player1.showHand(handShape)]);
                System.out.println(player2.getName() + " shows " + handShapeName[player2.showHand(handShape)]);         
                
                System.out.println(player1.findWinner(player2) + "  wins!");
        }
}

Suppose that we throw balls into m bins until some bin contains two balls. Each throw
is independent, and each ball is equally likely to end up in any bin. What is the expected number of
ball throwed?

How do I get numbers and words before I press the enter?

For example, if i type cat 12 Rabbit 27 and then click enter, i want to stop receiving input.

Consider a simple system with 8-bit block size. Assume the encryption (and decryption) to be a simple XOR of the key with the input. In other words, to encrypt x with k we simply perform x⊕k giving y. Similarly, to decrypt y, we perform y⊕k giving x.

You are given the following 16-bit input 1A2Bin hexadecimal. You are provided IV as 9D in hexadecimal. The key to be used (where appropriate) is 7C in hexadecimal. Compute the encrypted output with the following methods. Express your final answer, for each of them, as 4 hexadecimal characters so it is easy to read.

A. ECB

B. CBC

C. OFB

D. CFB

Assignment

Examine the Main and Address classes. You are going to add two classes derived from Address: BusinessAddress and PersonAddress.

Create BusinessAddress class

1. Select package home and create a new Java class called BusinessAddress
2. Make the class extend the Address class
3. Add two private String fields businessName and address2
4. Generate constructor and all getters and setters
5. Add a printLabel() method

The printLabel method should print (using System.out.println())

First line – the businessName field

Second line – the address2 field if it is not null or empty

Third line – the StreetAddress field if it is not null or empty

Fourth line – city field followed by a comma and space, the state field followed by two spaces, and the zip field

Create PersonAddress class

1. Select package home and create a new Java class called PersonAddress
2. Make the class extend the Address class
3. Add a private String field personName
4. Generate constructor and all getters and setters
5. Add a printLabel() method

The printLabel method should print (using System.out.println())

First line – the personName field

Second line – the StreetAddress field

Third line – city field followed by a comma and space, the state field followed by two spaces, and the zip field

Modify Main class

Add the following three BusinessAddress objects to the list.

Add the following three PersonAddress objects to the list.

write the outline pseudocode (code is also allowed) for the following problem...

Catherine wants to simulate a lottery game. What steps would this require?

Imagine that Catherine wants a computer to simulate a lottery game. The computer will be generating two-digit numbers. Each time the computer generates a number, the user is first invited to guess what the number is. If the user guesses the exact number, the award is 10 000 EUR. If the user makes a correct guess on one of the digits, and on the right place, the award is 3 000 EUR. If the user guesses correctly that a digit was selected, but not which position it is in, the award is 100 EUR.

Examples:

Computer: 96: Computer: 47: Computer: 42:

User: 96 User: 43 User: 29

Award Award Award

10 000 EUR 3 000 EUR

100 EUR

Catherine’s algorithm and program can follow the below-mentioned steps:

Step 1: The computer generates a random two-digit number.

Step 2: The user makes a guess of what the number is and enters it through the keyboard.

Step 3: The computer compares the two numbers and evaluates whether the user wins anything.

Step 4: The computer displays the number that was generated in step 1.
Step 5: the computer displays a message of whether the user wins something, as suggested

above.

Step 6: The computer repeats the procedure from step 1 to step 5. The game is played 3 times.
