Coupon collector is a classic statistic problem with many practical applications. The problem is to pick objects from a set of objects repeatedly and determine how many picks are needed for all the objects to be picked at least once. A variation of the problem is to pick cards from a shuffled deck of 52 cards repeatedly and find out how many picks are needed before you see one of each suit. Assume a picked card is placed back in the deck before picking another. Write a program to simulate the number of picks needed to get total of four cards from each different suit and display the four cards picked (it is possible that a card may be picked twice). Here is a sample run of the program:
4 of Diamonds
8 of Spades
Queen of Clubs
8 of Hearts
Number of picks: 9

Answer 1

Answer:

Here is the JAVA program:

public class Main { //class name

public static void main(String[] args) { //start of main method

//sets all boolean type variables spades, hearts diamonds and clubs to false initially

boolean spades = false;

boolean hearts = false;

boolean diamonds = false;

boolean clubs = false;

String[] deck = new String[4]; //to store card sequence

int index = 0; //to store index position

int NoOfPicks = 0; //to store number of picks (picks count)

while (!spades || !hearts || !diamonds || !clubs) { //loop starts

String card = printCard(getRandomCard()); //calls printCard method by passing getRandomCard method as argument to it to get the card

NoOfPicks++; //adds 1 to pick count

if (card.contains("Spades") && !spades) { //if that random card is a card of Spades and spades is not false

deck[index++] = card; //add that card to the index position of deck

spades = true; //sets spades to true

} else if (card.contains("Hearts") && !hearts) { //if that random card is a card of Hearts and hearts is not false

deck[index++] = card;

hearts = true; //sets hearts to true

} else if (card.contains("Diamond") && !diamonds) { //if that random card is a card of Diamond and diamonds is not false

deck[index++] = card;

diamonds = true; //sets diamonds to true

} else if (card.contains("Clubs") && !clubs) { if that random card is a card of Clubs and clubs is not false

deck[index++] = card;

clubs = true; } } //sets clubs to true

for (int i = 0; i < deck.length; i++) { //iterates through the deck i.e. card sequence array

System.out.println(deck[i]); } //prints the card number in deck

System.out.println("Number of picks: " + NoOfPicks); } //prints number of picks

public static int getRandomCard() { //gets random card

return (int) (Math.random() * 52); } //generates random numbers of 52 range

public static String printCard(int cardNo) { //displays rank number and suit

String[] suits = { "Spades", "Hearts", "Diamonds", "Clubs", }; //array of suits

String[] rankCards = { "Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10",

"Jack", "Queen", "King" }; //array of rank

int suitNo = cardNo / 13; //divides card number by 13 and stores to suitNo

int rankNo = cardNo % 13; //takes modulo of card number and 13 and store it to rankNo

return rankCards[rankNo] + " of " + suits[suitNo]; }} //returns rankCard at rankNo index and suits at suitNo index

Continuous Improvement

Explanation:

Continuous Improvement is a set of processes many companies use to evaluate and improve their overall operations on an ongoing basis. Usability testing Continuous Improvement Analytics System implementation.

What is Continuous Improvement?

W. Edwards Deming used the phrase "continuous improvement" to refer to general processes of improvement and to embrace "discontinuous" improvements, or many diverse ways addressing various topics.

A subset of continuous improvement, with a more narrow focus on linear, incremental change inside an already-existing process, is continuous improvement.

Some practitioners also believe that statistical process control techniques are more closely related to continuous improvement. Constant improvement, often known as continuous improvement, is the continued enhancement of goods, services, or procedures through both small-scale and significant advancements.

Answer:

You need to use the name and password of the main owner of the computer/the account you made when you first got it. Then, you should be able to download apps and use it if you have your apple ID set up.

Explanation:

Write some code that assigns True to the variable is_a_member if the value assigned to member_id can be found in the current_members list. Otherwise, assign False to is_a_member. In your code, use only the variables current_members, member_id, and is_a_member.

Answers

Answer:

current_members = [28, 0, 7, 100]

member_id = 7

if member_id in current_members:

is_a_member = True

else:

is_a_member = False

print(is_a_member)

Explanation:

Although it is not required I initialized the current_members list and member_id so that you may check your code.

After initializing those, check if member_id is in the current_members or not using "if else" structure and "in" ("in" allows us to check if a variable is in a list or not). If member_id is in current_members, set the is_a_member as True. Otherwise, set the is_a_member as False.

Print the is_a_member to see the result

In the example above, since 7 is in the list, the is_a_member will be True

A program is written to compute the sum of the integers from 1 to 10. The programmer, well trained in reusability and maintainability, writes the program so that it computes the sum of the numbers from k to n. However, a team of security specialists scrutinizes the code. The team certifies that this program properly sets k to 1 and n to 10; therefore, the program is certified as being properly restricted in that it always operates on precisely the range 1 to 10.

Required:
List different ways that this program can be sabotaged so that during execution it computes a different sum, such as 3 to 20.

Answers

Answer:

See explanation

Explanation:

An instance of such program written in python is

isum = 0

for i in range(1,11):

isum = isum + i

print(sum)

One of the ways the program can give a wrong result is when someone alters the program source program before it's complied and executed.

Take for instance.

Changing

isum = 0 to isum = 4

will alter the result by additional 4

Another way is if an outside program or process alters the program execution.

Implement a class Balloon that models a spherical balloon that is being filled with air. The constructor constructs an empty balloon. Supply these methods:

void addAir(double amount) adds the given amount of air.
double getVolume() gets the current volume.
double getSurfaceArea() gets the current surface area.
double getRadius() gets the current radius.

Supply a BalloonTester class that constructs a balloon, adds 100cm^3 of air, tests the three accessor methods, adds another 100cm3 of air, and tests the accessor methods again.

Answers

Answer:

Here is the Balloon class:

public class Balloon { //class name

private double volume; //private member variable of type double of class Balloon to store the volume

public Balloon() { //constructor of Balloon

volume = 0; } //constructs an empty balloon by setting value of volume to 0 initially

void addAir(double amount) { //method addAir that takes double type variable amount as parameter and adds given amount of air

volume = volume + amount; } //adds amount to volume

double getVolume() { //accessor method to get volume

return volume; } //returns the current volume

double getSurfaceArea() { //accessor method to get current surface area

return volume * 3 / this.getRadius(); } //computes and returns the surface area

double getRadius() { //accessor method to get the current radius

return Math.pow(volume / ((4 * Math.PI) / 3), 1.0/3); } } //formula to compute the radius

Explanation:

Here is the BalloonTester class

public class BalloonTester { //class name

Explanation:

An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.

Simply stated, access control is the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.

Basically, authentication is like an access control, ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification

An example of an access control is a password because it is typically a basic and fundamental front-line defense mechanism against an unauthorized use of data or cyber attacks from hackers.

12.18 Lab - Structs
In this lab, you will familiarize yourself with structs through a small exercise. We will be mixing the RGB values of colors together to make a new one.
RGB stands for red, green and blue. Each element describes the intensity value ranging from 0 - 255. For example: black color will have RGB values (0, 0, 0) while white will have (255, 255, 255).
Create an array of structs color. The struct contains three integers named red, green and blue. This corresponds to the RGB values of a color. For each array element, ask the user to enter the intensity value of red, green and blue. The value should be between 0 and 255 (inclusive).
*********The user can enter at most 10 colors. ********. see below for inputs
Additionally, compute the average of each of the red, green and blue components. For code modularity, implement a function that returns the average of each rgb component in your dynamic array. The function (called average) should take in a struct array, the rgb type for which you want to compute the average (as a string - red, blue or green) and its length. Print out the final result in the form (r, g, b), where r, g, b corresponds to each averaged value.
Can you guess what color you mixed? (Note: Your program does not need to print the final color mixed)

The Beaufort Wind Scale is used to characterize the strength of winds. The scale uses integer values and goes from a force of 0, which is no wind, up to 12, which is a hurricane. The following script first generates a random force value. Then, it prints a message regarding what type of wind that force represents, using a switch statement. You are to rewrite this switch statement as one nested 150 CHAPTER 4: Selection Statements if-else statement that accomplishes exactly the same thing. You may use else and/or elseif clauses.

Write a program named palindromefinder.py which takes two files as arguments. The first file is the input file which contains one word per line and the second file is the output file. The output file is created by finding and outputting all the palindromes in the input file. A palindrome is a sequence of characters which reads the same backwards and forwards. For example, the word 'racecar' is a palindrome because if you read it from left to right or right to left the word is the same. Let us further limit our definition of a palindrome to a sequence of characters greater than length 1. A sample input file is provided named words_shuffled. The file contains 235,885 words. You may want to create smaller sample input files before attempting to tackle the 235,885 word sample file. Your program should not take longer than 5 seconds to calculate the output

If you can adjust my code to get program running that would be ideal, but if you need to start from scratch that is fine.

Open your python-3 console and import the following .py file

#necessary to import file

import sys

#define function

def palindrome(s):

return len(s) > 1 and s == s[::-1]

def main():

if len(sys.argv) < 3:

print('Problem reading the file')

exit(1)

file_input = sys.argv[1]

file_output = sys.argv[2]

try:

with open(file_input, 'r') as file open(file_output, 'w') as w:

for raw in file:

raw = raw.strip()

#call function

if palindrome(raw.lower()):

w.write(raw + "\n")

except IOError:

print("error with ", file_input)

if __name__ == '__main__':

main()

How do the following technologies help you on your quest to become a digital citizen

Answers

Answer:

kiosks

Explanation:

It is generally believed that a digital citizen refers to a person who can skillfully utilize information technology such as accessing the internet using computers, or via tablets and mobile phones, etc.

Kiosks (digital kiosks) are often used to market brands and products to consumers instead of having in-person interaction. Interestingly, since almost everyone today goes shopping, consumers who may have held back from using digital services are now introduced to a new way of shopping, thus they become digital citizens sooner or later.

Create a function min_mid_max which takes a list as its formal parameter and returns a new list with the following characteristics: element 0 contains the minimum value • element 1 contains the middle value (not the median -- which would require an average if the list had an even number of elements). If the list is even (e.g. [1,2,3,4]) the 'middle' value will be the right value of the two possible choices (e.g. 3 rather than 2). • element 2 contains the maximum value Notes: • You can only use Python syntax shown so far (even if you know more) • You cannot use any math library (we have yet to see this) • You should use the function sorted. Remember the function sorted does not change its input, it returns a new list. • You should only need to call sorted one time. print(sorted(3,2,1])) • You can use the function int (another built in function) to help determine the index of the middle value. This function takes a floating point (or any kind of number) and converts it into an integer (e.g.print(int(4.32)). This will allow you to treat lists with an even number of elements the same as a list with a odd number of elements. • If min_mid_max is called with an empty list, return an empty list. • If min_mid_max is called with 1 item that item is the min, mid, and the max • If min_mid_max is called with 2 items, the mid and the max should be the same • No need to worry about the incoming list being the value None

Answers

Answer:

Follows are the code to this question:

def min_mid_max(myList):#defining a method min_mid_max that accept a list in parameter

if len(myList)==0:#defining if block that check list length equal to 0

return []#return empty list

s = sorted(myList)#defining variable s that uses the sorted method to sort the list

m = int(len(myList)/2)#defining mid variable that hold list mid value

return [s[0], s[m], s[-1]]#return list values

print(min_mid_max([1,2,3,4]))#use print function to call method

print(min_mid_max([]))#use print function to call method

print(min_mid_max([1, 2]))#use print function to call method

print(min_mid_max([1]))#use print function to call method

Output:

Please find the attached file.

Explanation:

In the given code, a method "min_mid_max" is defined, which accepts a list "myList" in parameter, inside the method if block is used, that check length of the list.

If it is equal to 0, it will return an empty list, otherwise, a variable "s" is declared, that use the sorted method to sort the list, and in the "m" variable, it holds the mid number of list and returns its value.

In the print method, we call the above method by passing a list in its parameter.

In point a:

It utilizes multiple algorithms based on machine learning can understand the attributes or transform their probability into projections. Its algorithms could be used, including such neural computer systems or artificial neural networks. Whenever the input, as well as the target outcome, are taken their possibilities are converted in forecasts, so that if the input, as well as the corresponding results, are balanced.

In point b:

The operating curves of its receiver is indeed a plot of its true positives for its incorrect positive rate. It could be used in different tests for treatment. It indicates the variations of its responsiveness between all the two components and also the accuracy. Line slopes supply LR with a value.

As a twist on the Hello World exercise, you are going to be the end user of the Hello class. This class is designed to greet the user in a variety of world languages. For this task, complete the following:
Use the Scanner class to ask the user for their name.
Create a Hello object by passing the name to the constructor.
Call at least 3 methods from the Hello class to print the greeting in 3 different languages.
Remember to write your code in the HelloTester class, but make sure you take a look at the Hello class so that you know the names of the methods you need to use.

Answers

Answer:

Here is the Hello class:

public class Hello { //class name

private String name; //to store the name

public Hello (String names) //parameterized constructor

{ name = names; }

public void English() { //method to greet user in english

System.out.print("Hello "); //displays Hello on output screen

System.out.print(name); //displays user name

System.out.println("!"); } //displays exclamation mark symbol

public void Spanish(){ //method to greet user in spanish

System.out.print("Hola "); //displays Hello on output screen

System.out.print(name); //displays user name

System.out.println("!"); } //displays exclamation mark symbol

public void French() { //method to greet user in french

System.out.print("Bonjour "); //displays Hello on output screen

System.out.print(name); //displays user name

System.out.println("!"); } } //displays exclamation mark symbol

Explanation:

Here is the HelloTester class:

import java.util.Scanner; //to accept input from user

public class HelloTester { //class name

public static void main (String[]args) { //start of main method

String name; //to store the name of user

Scanner input = new Scanner(System.in); //creates Scanner class object

System.out.println("Enter name?" ); //prompts user to enter name

name = input.nextLine(); //scans and reads the name from user

Hello hello = new Hello(name); //creates Hello class object and calls constructor by passing name

hello.English(); //calls English method using object hello to greet in english

hello.Spanish(); //calls Spanish method using object hello to greet in spanish

hello.French(); } } //calls French method using object hello to greet in french

The output of the program is:

Enter name? user Hello user! Hola user! Bonjour user!

The screenshot of the program along with its output is attached.
