g Create a Java program that takes input of a list of integers from the user, stores them into an array and then finally uses the array contents to output the list of integers in reverse. The user's input begins with the number of integers to be stored in the array. For coding simplicity, follow each output integer by a space, including the last one. Assume that the list will always contain fewer than 20 integers.Create a Java program Ex: If the input is: 8 5 2 3 4 10 6 8 9
Answer:
import java.util.Scanner;
public class Main{
public static void main(String[] args) {
int arraylent;
Scanner input = new Scanner(System.in);
System.out.print("Array Length: ");
arraylent= input.nextInt();
int[] myarray = new int[arraylent];
for(int i = 0; i<arraylent;i++)
myarray[i] = input.nextInt();
for(int i = arraylent-1; i>=0;i--)
System.out.println(myarray[i]);
}
}
Explanation:
This declares the length of the array
int arraylent;
This next two lines prompt and get the array length i.e. number of input
System.out.print("Array Length: ");
arraylent= input.nextInt();
This declares the array as type integer. And the length of the array is gotten from the user input
int[] myarray = new int[arraylent];
This gets the items of the array
for(int i = 0; i<arraylent;i++)
myarray[i] = input.nextInt();
This reverse and prints the array
for(int i = arraylent-1; i>=0;i--)
System.out.println(myarray[i]);
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.
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()
Output:
Please find the attached file.
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.

A specific packet journey, from your computer to a remote server, end-to-end across multiple networks, has the following link bandwidths (packet travels across each of these links, in order): 1000 Mbps, 1 Mbps, 40 Mbps, 400 Mbps, 100 Mbps, 1000 Mbps. Assuming your computer and the server can transfer data at > = 1000 Mbps (so neither device is limiting the data transfer relative to the links), how long, in seconds, will it take to transfer a 125 MB file?
Answer:
0.125 seconds
Explanation:
The formula for the time taken to transfer the file is = file size / bandwidth
Assuming the computer and server could only transfer data at the speed of 1000 Mbps or more, The time of transmission is;
= 125 MB / 1000 Mbps = 0.125 seconds.

import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Length of array: ");
int len = input.nextInt();
int[] intArray = new int[len];
for(int i = 0; i<len;i++){
intArray[i] = input.nextInt();
}
for(int i = len-1; i>=0;i--){
System.out.print(intArray[i]+" ");
}
}
}
Explanation:
This line prompts user for length of array
System.out.print("Length of array: ");
This gets the length of the arrau
int len = input.nextInt();
This declares the array as integer
int[] intArray = new int[len];
The following iteration gets input to the array
for(int i = 0; i<len;i++){
intArray[i] = input.nextInt();
}
The following iteration prints the array in reversed order
for(int i = len-1; i>=0;i--){
System.out.print(intArray[i]+" ");

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

Adam is so good at playing arcade games that he will win at every game he plays. One fine day as he was walking on the street, he discovers an arcade store that pays real cash for every game that the player wins - however, the store will only pay out once per game. The store has some games for which they will pay winners, and each game has its own completion time and payout rate. Thrilled at the prospect of earning money for his talent, Adam walked into the store only to realize that the store closes in 2 hours (exactly 120 minutes). Knowing that he cannot play all the games in that time, he decides to pick the games that maximize his earnings
Sample game board at the arcade GAME COMPLETION TIME (in minutes) PAYOUT RATE Pac-man 90 400 Mortal Kombat 10 30 Super Tetris 25 100 Pump it Up 10 40 Street Fighter II 90 450 Speed Racer 10 40
An acceptable solution is the one where it still picks the best earnings even when the list of games or completion times or payout rates change.
Question:
Write code in Java/Scala/Python to help Adam pick the sequence(s) of games that earn him the most money?.
Then, assume you have a variable list of games and their payout rates. What is the best way to pick the games that earn you the most?
Input Explanation
The first line of input is always an integer denoting many lines to read after the first line. In our sample test case, we have 6 in the first line and 6 lines after the first line, each having a game, completion_time and payout_rate.
In each data line, the game, completion_time and payout_rate are separated by a ','(comma).
The games board may change but the store still closes in 120 minutes.
Input

what type of collection is used in the assignment statement
info: [3:10,4:23,7:10,11:31]
tuple
list
Duque
dictionary
Answer:
The correct answer to this question is given below in the explanation section.
Explanation:
There are four data types in Python used to store data such as tuple, list, set, and dictionary.
The correct answer to this question is option D: Dictionary
Dictionary data type is used to store data values in key:value pairs as given in the question. It is a collection that is changeable, unordered, and does not allow duplicate entries.
Dictionaries in Python are written with curly brackets and have keys and values such as car={name="honda", model=2010}
when you run the given assignment statment such
info= {3:10,4:23,7:10,11:31}
print(info)
It will print the info dictionary (key:value pair)
{3: 10, 4: 23, 7: 10, 11: 31}
While other options are not correct because:
Tuples in Python are used to store multiple items in a single variable. For example:
info=("apple", "banana", "cherry")
List is used to store multiple items in a single variable. for example
myList = ["apple", "banana", "cherry"]
print(myList)
The list is ordered, changeable, and allows duplicate entry. But you can not put key: value pair in the list.

Review how to write a for loop by choosing the output of this short program.
for counter in range(3):
print(counter * 2)
Please explain it to me, I’m not learning Bc I don’t have a teacher.
Answer:
The output is:
0
2
4
Explanation:
First of all, the print statement must be indented with a tab, otherwise it is not part of the for loop.
The range(3) creates an array with values 0,1,2. The variable 'counter' gets those values one after another, and the print statement outputs this value doubled, hence the 0, 2 and 4 output.

A hacker successfully modified the sale price of items purchased through your company's web site. During the investigation that followed, the security analyst has verified the web server, and the Oracle database was not compromised directly. The analyst also found no attacks that could have caused this during their log verification of the Intrusion Detection System (IDS). What is the most likely method that the attacker used to change the sale price of the items purchased
Answer:
By modifying the hidden form values that is in a local copy of the company web page
Explanation:
In a situation were the hacker successful change the price of the items he/she purchased through the web site of the company's in which the company web server as well as the company Oracle database were not compromised directly which means that the most likely method in which the attacker used to modified the sale price of the items he/she purchased was by modifying the HIDDEN FORM VALUE that was in the local copy of the company web page making it easy for the HIDDEN FORM VALUE to be vulnerable to the hacker because the hidden form value did not store the company server side information or data but only store the company software state information which is why HIDDEN FORM VALUE should not be trusted.
