Answer:
import java.util.Scanner;
public class Countdown {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int n;
System.out.print("Please enter a number to start: ");
n = input.nextInt();
System.out.print(countdown(n));
}
public static String countdown(int number) {
if(number>0) { return " "+number+countdown(number-1); }
else { return " Blastoff!"; }
}
}
Explanation:
The main method begins here
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
This declares an integer variable n
int n;
This prompts user for a number
System.out.print("Please enter a number to start: ");
This gets user input n
n = input.nextInt();
This calls the countdown function
System.out.print(countdown(n));
}
The countdown function begins here
public static String countdown(int number) {
This is the base case where input number is greater than 0
if(number>0) { return " "+number+countdown(number-1); }
This ends the recursion
else { return " Blastoff!"; }
}

This is similar to the last problem, except that the first number on a line is an ID number that identifies an account. The same ID number may appear on any number of lines. Use a Dictionary to accumulate, for each ID, the sum of all the numbers that are on all the lines with that ID number. Call the input file id_data.txt. Write an output file called ID_sums.txt. On each line of the output fille, print an ID number and the sum. Sort the lines by the numerical order of the IDs
Answer:
Following are the code to this question:
def getSum(ID):#defining a method getSum that accept an ID
t= 0#defining a variable t
while ID!= 0:#defining while loop to check ID not equal to 0
t+= ID % 10# holding remainder value
ID = ID // 10#holding quotient value
return t#return total value
def readRecord(S):#defining a method readRecord that hold list
f_Read = open("idInfo.txt","r")#defining a variable f_Read to open file
for C_ID in f_Read:#defining for loop to hold file value
C_ID = C_ID.replace('\n', '')#use replace method
S[C_ID] = getSum(int(C_ID))#use list to method value
f_Read.close()#close file
def sortRecord(ID_List, t_List):#defining a sortRecord
for x in range(len(ID_List) - 1):#defining for loop to calculate the length of list
for y in range(0, len(ID_List) - x - 1):#defining for loop to calculate the length of list
if ID_List[y] > ID_List[y+1]:#defining if block to check value is greater
ID_List[y], ID_List[y+1] = ID_List[y+1], ID_List[y]#swap the value
t_List[y], t_List[y+1] = t_List[y+1], t_List[y]#swap the value
def showReport(ID, t):#defining a method showReport that accept id and t
for i in range(len(ID)):#defining for loop to hold index value
print(ID[i]," ",t[i])#print index value
def writeRecord(ID_List, t_List):#defining a method writeRecord that accept two list
f_Write = open("idSorted.txt","w")#defining a variable f_Write to hold store value in file
for i in range(len(ID_List)):#defining a for loop to store value with index
f_Write.write(ID_List[i])#hold list value
f_Write.write(" ") #for space
f_Write.write(str(t_List[i]) + "\n")# add index value
f_Write.close()#close file
def run():#defining method run
S = {}#defining an empty list
readRecord(S)#passing list into readRecord method
ID_List = list(S.keys())#defining a variable that holds key value in list
t_List = list(S.values())#defining a variable that holds values value in list
sortRecord(ID_List, t_List)#calling a method sortRecord by passing value
showReport(ID_List, t_List)#calling a method showReport by passing value
writeRecord(ID_List, t_List)#calling a method writeRecord by passing value
if "run":
run()

Explanation:
In the above program code, 6 method getSum, readRecord, sortRecord,showReport, writeRecord, and run method is defined, in which getSum and readRecord is used a single list store value in parameters, and in other methods, it accepts two parameter to store value in key and values form and use a txt file to store and take value.
In the run method, an empty list s is declared, that pass into the variable ID_List and t_List, and call the method, in this program two a text file "idInfo.txt" is used, that holds some value in the file, and create another file that is "idSorted.txt", in this file it stores the value in the numerical order of the ID's.
I am having trouble with doing this code on Python:Develop the Car class by creating an attribute purchase_price (type int) and the method print_info() that outputs the car's information.Ex: If the input is:2011 18000 2018where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, then print_info() outputs:Car's information: Model year: 2011 Purchase price: 18000 Current value: 5770Note: print_info() should use three spaces for indentation.
Answer:
class Car:
def __init__(self, model_year, purchase_price):
self.model_year = model_year
self.purchase_price = purchase_price
self.current_year = 0
self.current_value = 0
def set_current_year(self, year):
self.current_year = year
def calc_current_value(self, current_year):
if self.current_year == 0:
return "Must first input the current year"
depreciation_rate = 0.15
car_age = current_year - self.model_year
self.current_value = round(self.purchase_price - (car_age * (self.purchase_price * 0.15)))
def print_info(self):
print("Car's information:")
print(f"Model year: {self.model_year}")
print(f"Purchase price: {self.purchase_price}")
if self.current_value > 0:
print(f"Current value: {self.current_value}")
else:
print("Current value: Unknown")
Explanation:
The python program above defines the class "Car" that accepts the model year and purchase price of an instance. The class has a set method for the current year variable that is used to calculate and update the current value variable of the object. The print_info method prints the car model year, purchase price and its current value after nth years.

The U.S. military's standard for computer security is known as
DCS-3000.
TEMPEST.
Daubert standard.
Carnivore.
Answer:
TEMPEST.
Explanation:
TEMPEST is an acronym for Telecommunications Electronics Materials Protected from Emanating Spurious Transmissions and it is a secret (classified) project of the government of the United States of America that originated with its military in the 1960s based on the study of security with respect to telecommunication devices emitting Electromagnetic Radiation (EMR).
Hence, the U.S. military standard for computer security is known as TEMPEST.
The main purpose of the Telecommunications Electronics Materials Protected from Emanating Spurious Transmissions (TEMPEST) is to prevent the theft, compromise or interception of informations that are being transmitted on various telecommunications devices through the use of Electromagnetic Radiation (EMR).
Jorge is sending a message to Thomas but would like a copy sent to his external email address as well. Jorge does not want Thomas to see this copy that was sent.
Which mail field will Jorge use to achieve this goal?
To:
From:
CC:
BCC:
Answer: BCC (fourth choice)
=================================================
Explanation:
CC stands for "carbon copy".
BCC stands for "blind carbon copy".
Filling out forms is a tedious process. It's even more tedious when you have to repeat yourself multiple times. Carbon copy paper technology allows you to fill out one form and have those inputted entries be copied to the layers below. In terms of email, a carbon copy (CC) email is just an email sent to more than one person. In the CC line, recipients can see who the other people are in the email chain.
In contrast, a blind carbon copy is where the recipients cannot see who is in the BCC line. This allows Jorge to send the message copy to an external address without Thomas knowing.

The attenuation of a signal is -10 dB. What is the final signal power if it was originally
5 W?
Answer:
P₂ = 0.5 W
Explanation:
It is given that,
The attenuation of a signal is -10 dB.
We need to find the final signal power if it was originally 5 W.
Using attenuation for signal :
[tex]dB=10\text{log}_{10}(\dfrac{P_2}{P_1})[/tex]
Put dB = -10, P₁ = 5 W
Put all the values,
[tex]-10=10\text{log}_{10}(\dfrac{P_2}{5})\\\\-1=\text{log}_{10}(\dfrac{P_2}{5})\\\\0.1=\dfrac{P_2}{5}\\\\P_2=5\times 0.1\\\\P_2=0.5\ W[/tex]
So, the final signal power is 0.5 W.
The final signal power if it was originally 5W is; 0.5 W
Signal PowerWe are given;
Attenuation signal; dB = -10 dBOriginal signal power; P1 = 5 WFormula for attenuation signal is;
dB = 10log_10_ (P2/P1)
Where P2 is final signal power
Thus;
-10 = 10log_10_(P2/5)
-10/-10 = log_10_(P2/5)
-1 = log_10_(P2/5)
0.1 = P2/5
P2 = 0.1 × 5
P2 = 0.5 W
