Hi everyone,
for my undergraduate research project, I'm looking for an R code for agglomerative clustering. Basically, I need to know what happened inside hclust method in R. I have looked everywhere but don't find a proper way to combine 2 data points that have the smallest distance. I was stuck at developing a dissimilarity matrix after the first phase of dissimilarity matrix generation(literally I have generated the first dissimilarity matrix). I'm not specifying R, if anyone could give me a solution in any language I would gratefully accept that.

For this exercise, you are going to complete the printScope() method in the Scope class. Then you will create a Scope object in the ScopeTester and call the printScope.
The method will print the name of each variable in the Scope class, as well as its corresponding value. There are 5 total variables in the Scope class, some of which can be accessed directly as instance variable, others of which need to be accessed via their getter methods.
For any variable that can be accessed directly, use the variable name. Otherwise, use the getter method.
Sample Output:
The output of the printScope method should look like this:
a = 5
b = 10
c = 15
d = 20
e = 25
public class ScopeTester
{
public static void main(String[] args)
{
// Start here!
}
}
public class Scope
{
private int a;
private int b;

The information technology (IT) department of a real-estate group cosponsored a data warehouse with a County governement. In the formal proposal written by the IT team, costs were estimated at 8,000,000/- the project’s duration was estimated to be eight months, and the responsibility for funding was defined as the business unit’s. The IT department proceeded with the project before it even knew if the project had been accepted. The project actually lasted two years because requirements gathering took nine months instead of one and a half, the planned user base grew from 200 to 2,500, and the approval process to buy technology for the project took a year. Three weeks before technical delivery, the IT director canceled the project. This failed endeavor cost the organization and taxpayers 25,000,000/-.

a. A numeric keypad.
b. An interpreter.
c. A 3D printer.
d. A speaker.
Explanation:
An output device can be defined as a hardware device that typically receives processed data from the central processing unit (CPU) and converts these data into information that can be used by the end user of a computer system.
Also, an input device can be defined as any device that is typically used for sending data to a computer system.
Generally, all of the output and input device of a computer are known as peripheral (external) devices and they provide data (informations) to the end users in various formats such as video, audio, texts, images etc.
Since output and input devices are peripheral (external) devices, they can be connected to the computer system wirelessly or through a wired-connection (cable).
Some examples of peripheral (external) devices are monitor, speakers, keyboard, printer, mouse, scanner, projector etc.
Basically, the three (3) key element of a computer system are: a set of memory modules, processor and a set of input-output (I/O) modules. Each of the input-output (I/O) module interfaces to the central switch or system bus and are used to control one or more peripheral (external) devices.
a. A numeric keypad is a device used to input a PIN. It comprises of numbers ranging from 0 to 9.
b. An interpreter analyses and executes a program line by line.
c. A 3D printer produces output in the form of solid objects. It is typically used for inscribing or printing textual informations or graphic images on an object in three dimensions.
d. A speaker produces output in the form of sound. It is an electronic device that converts electrical signals into sound energy (waves).
Assume a future where security counter measures against DoS attacks are much more widely implemented than at present. In this future network, anti-spoofing and directed broadcast filters are widely deployed. Also, the security of PCs and workstations is much greater, making the creation of botnets difficult. Do the administrators of server systems still have to be concerned about, and take further countermeasures against, DoS attacks? If so, what types of attacks can still occur, and what measures can be taken to reduce their impact? Explain in detail with valid diagram and example.
Answer:
yes administrators have to be concerned
Explanation:
It is necessary for countermeasures to be taken against DoS attacks
The types of attacks that can still occur are:
If the network connection get to be overloaded, there could be flash crown of this computer system and fraudulent activities maybe initiated. By flash crowd we mean that the there is a great deal of traffic on the system and this could cause the network connection to be destroyed.
To reduce the impact of this kind of attacks,
1. there should be enough or excess network bandwidth and distributed servers should be replicated if there is a possibility that network could get to be overloaded.
2. restriction is more commonly done on sporting sites. Restriction brings about an increase in implementation cost.
3. The impact of this type of attack can be reduced by stopping unwanted traffic throught the implementation of filters
4. Use strong antivirus on computer sytems that are used to connect to the internet

It is desired to create a mortgage estimator by writing a program containing a function. The user inputs the amount of loan (L), the loan term in number of months (W, and the annual interest rate (D in the script. The script then makes use of a function that accepts these values as inputs through its argument and calculates and returns the monthly payment and the total payments over the life of the loan. The monthly payment and the total payment could be calculated using the following expressions:
monthly payment 1-(1+ 1 112) N I/12 total payment Nxmonthly payment
Note that the interest rate must be expressed in decimal; for example, if the interest rate is 8% it must be entered as 0.08 Test your program for several scenarios and submit the results with the program listing.
The values of L, I, monthly payment, and total payment should be written to a file as shown below:
Interest Loan Amount Interest Months Monthly Payment Total Payment
0.06 10000 36
108 120000 0.05
0.07 85000 48
0.08 257000 240
0.05 320000 120
Answer:
In Python:
L = int(input("Loan Amount: "))
N = int(input("Months: "))
I = float(input("Annual Interest Rate: "))
monthly_payment = round(L/((1 - (1 + I/12)**(-N))/(I/12)),2)
total_payment = round(N * monthly_payment,2)

Explanation:
The next three lines get the required inputs
L = int(input("Loan Amount: "))
N = int(input("Months: "))
I = float(input("Annual Interest Rate: "))
Calculate the monthly payment
monthly_payment = round(L/((1 - (1 + I/12)**(-N))/(I/12)),2)
Calculate the total payment
total_payment = round(N * monthly_payment,2)
Open the output file

X274: Recursion Programming Exercise: Cannonballs Spherical objects, such as cannonballs, can be stacked to form a pyramid with one cannonball at the top, sitting on top of a square composed of four cannonballs, sitting on top of a square composed of nine cannonballs, and so forth.
RequireD:
Write a recursive function that takes as its argument the height of a pyramid of cannonballs and returns the number of cannonballs it contains.
Answer:
The function in C is as follows:
#include <stdio.h>
int C_ball(int height){
if(height == 1) {
return 1;}
return (height * height) + C_ball(height - 1);}
int main(){
int n;
printf("Height: ");
scanf("%d",&n);
printf("Balls: %d",C_ball(n));
return 0;
}
Explanation:
The function begins here
#include <stdio.h>
This defines the function
int C_ball(int height){
If height is 1, return 1
if(height == 1) {
return 1;}
This calls the function recursively
return (height * height) + C_ball(height - 1);}
The main begins here
int main(){
This declares the height as integer
int n;
This prompts the user for the height
printf("Height: ");
scanf("%d",&n);
This calls the function
printf("Balls: %d",C_ball(n));
return 0;
}

Write a program that picks up a secret number from 1 to 100 when the user starts the game and asks the
user to guess what number it is. If the user’s guess is correct, the program congratulates the user for the
perfect answer and then make it possible for the user to start a new game; otherwise, it will tell the user
that it is too high or too low and let the user continue to play.
In your program, you may use the following code to generate a random number from 1 to 100 as the
secret number for a new game.
import random
number = random.randint(1, 100)
In addition, your program will keep track of the number of guesses the user made and display the number
of guesses when a game is over. If a user is successful by more than 7 tries, display an additional message
to tell the user to consider a different strategy in order to improve one’s performance.
Given below is a typical dialog between a user and your program when the user uses your program.
Hello, what is your name? John
John, I am thinking a number between 1 and 100 (both included).
Can you guess what it is?
Guess a number (1-100): 50
Your guess is too high. Try again.
Guess a number (1-100): 25
Your guess is too low. Try again.
Guess a number (1-100): 35
Your guess is too low. Try again.

The file will consist of a single username and password per line with a space in between.
1. Begin by creating a class PasswordFile which has the following interface:
class PasswordFile
public:
PasswordFile(string filename); // opens the file and reads the names/passwords in the vectors user and password.
void addpw(string newuser, string newpassword); //this adds a new user/password to the vectors and writes the vectors to the file filename bool checkpw(string user, string passwd); // returns true if user exists and password matches
private:
string filename; // the file that contains password information
vector user; // the list of usernames
vector password; // the list of passwords
void synch(); writes the user/password vectors to the password file
The constructor accepts a filename, and reads the file one-line at a time and adds values to the vectors user and password. The function addpw adds a user/password pair to end of each vector.
2. Now create a password.txt file with some entries such as:
jsmith turtle
madams apple
Also create a main program to test your classes :
int main() PasswordFile passfile
("password.txt");
passfile.addpw("dbotting","123qwe");
