Answer:
n = n(n-1)!
Explanation:
expanding the factorial we get;
1!=1.
2!=2x1.
3!=3x2x1.
4!=4x3x2x1.
5!=5x4x3x2x1.
we can rewrite the above factorials as:
1!=1
2!=2!
3!=2!x3
4!=4x3!

a) File Server
b) Domain Controller
c) SQL Server
d) Internet Information Services (IIS)
Answer:
b) Domain Controller
Explanation:
Active Directory Rights Management Services (AD RMS) is a server software that is developed by Microsoft to manage information rights on the Windows server.
The AD RMS servers produce a rights account certificate to link various users with particular PC systems. They also issue end-user licenses.
To ensure that AD RMS network transmission is protected, the domain controller needs to be allowed to enroll for a computer certificate.
A domain controller is a server that authenticates requests from users on a particular computer network. It keeps user data organized and secure.

g Write a method that accepts a String object as an argument and displays its contents backward. For instance, if the string argument is "gravity" the method should display -"ytivarg". Demonstrate the method in a program that asks the user to input a string and then passes it to the method.
Answer:
The program written in C++ is as follows; (See Explanation Section for explanation)
#include <iostream>
using namespace std;
void revstring(string word)
{
string stringreverse = "";
for(int i = word.length() - 1; i>=0; i--)
{
stringreverse+=word[i];
}
cout<<stringreverse;
}
int main()
{
string user_input;
cout << "Enter a string: ";
getline (std::cin, user_input);
getstring(user_input);
return 0;
}
Explanation:
The method starts here
void getstring(string word)
{
This line initializes a string variable to an empty string
string stringreverse = "";
This iteration iterates through the character of the user input from the last to the first
for(int i = word.length() - 1; i>=0; i--) {
stringreverse+=word[i];
}
This line prints the reversed string
cout<<stringreverse;
}
The main method starts here
int main()
{
This line declares a string variable for user input
string user_input;
This line prompts the user for input
cout << "Enter a string: ";
This line gets user input
getline (std::cin, user_input);
This line passes the input string to the method
revstring(user_input);
return 0;

Write a Python program stored in a file q1.py to play Rock-Paper-Scissors. In this game, two players count aloud to three, swinging their hand in a fist each time. When both players say three, the players throw one of three gestures: Rock beats scissors Scissors beats paper Paper beats rock Your task is to have a user play Rock-Paper-Scissors against a computer opponent that randomly picks a throw. You will ask the user how many points are required to win the game. The Rock-Paper-Scissors game is composed of rounds, where the winner of a round scores a single point. The user and computer play the game until the desired number of points to win the game is reached. Note: Within a round, if there is a tie (i.e., the user picks the same throw as the computer), prompt the user to throw again and generate a new throw for the computer. The computer and user continue throwing until there is a winner for the round.
Answer:
The program is as follows:
import random
print("Rock\nPaper\nScissors")
points = int(input("Points to win the game: "))
player_point = 0; computer_point = 0
while player_point != points and computer_point != points:
computer = random.choice(['Rock', 'Paper', 'Scissors'])
player = input('Choose: ')
if player == computer:
print('A tie - Both players chose '+player)
elif (player.lower() == "Rock".lower() and computer.lower() == "Scissors".lower()) or (player.lower() == "Paper".lower() and computer.lower() == "Rock".lower()) or (player == "Scissors" and computer.lower() == "Paper".lower()):
print('Player won! '+player +' beats '+computer)
player_point+=1
else:
print('Computer won! '+computer+' beats '+player)
computer_point+=1
print("Player:",player_point)
print("Computer:",computer_point)
Explanation:
This imports the random module
import random
This prints the three possible selections
print("Rock\nPaper\nScissors")
This gets input for the number of points to win
points = int(input("Points to win the game: "))
This initializes the player and the computer point to 0
player_point = 0; computer_point = 0
The following loop is repeated until the player or the computer gets to the winning point
while player_point != points and computer_point != points:
The computer makes selection
computer = random.choice(['Rock', 'Paper', 'Scissors'])
The player enters his selection
player = input('Choose: ')
If both selections are the same, then there is a tie
if player == computer:
print('A tie - Both players chose '+player)
If otherwise, further comparison is made
elif (player.lower() == "Rock".lower() and computer.lower() == "Scissors".lower()) or (player.lower() == "Paper".lower() and computer.lower() == "Rock".lower()) or (player == "Scissors" and computer.lower() == "Paper".lower()):
If the player wins, then the player's point is incremented by 1
print('Player won! '+player +' beats '+computer)
player_point+=1
If the computer wins, then the computer's point is incremented by 1
else:
print('Computer won! '+computer+' beats '+player)
computer_point+=1
At the end of the game, the player's and the computer's points are printed
print("Player:",player_point)
print("Computer:",computer_point)
In what way does a hash provide a better message integrity check than a checksum (such as the Internet checksum)?
Answer:
Hash function have less collision than a internet checksum because of computational infeasibility.
Explanation:
A collision means there is more then one way to produce the same sum. It is nearly difficult to developed two messages with same hash however, in checksum, it is more easier to develop or modify two messages to have same sum, thereby enabling attackers to have access to the message or the information arising to less message integrity.

Your program should prompt the user to enter the Python source code filename
Answer:
Here is the Python program:
import keyword #module that contains list of keywords of python
filename = input("Enter Python source code filename: ") # prompts user to enter the filename of a source code
code = open(filename, "r") # opens the file in read mode
keywords = keyword.kwlist #extract list of all keywords of Python and stored it into keywords
dictionary = dict() #creates a dictionary to store each keyword and its number of occurrence in source code
for statement in code: # iterates through each line of the source code in the file
statement = statement.strip() # removes the spaces in the statement of source code
words = statement.split(" ") #break each statement of the source code into a list of words by empty space separator
for word in words:# iterates through each word/item of the words list
if word in keywords:#checks if word in the code is present in the keywords list of Python
if word in dictionary: #checks if word is already present in the dictionary
dictionary[word] = dictionary[word] + 1 #if word is present in dictionary add one to the count of the existing word
else: #if word is not already present in the dictionary
dictionary[word] = 1 #add the word to the dictionary and set the count of word to 1
for key in list(dictionary.keys()): #iterates through each word in the list of all keys in dictionary
print(key, ":", dictionary[key])# prints keyword: occurrences in key:value format of dict
Explanation:
The program is well explained in the comments attached with each line of the program.
The program prompts the user to enter the name of the file that contains the Python source code. Then the file is opened in read mode using open() method.
Then the keyword.kwlist statement contains the list of all keywords of Python. These are stored in keywords.
Then a dictionary is created which is used to store the words from the source code that are the keywords along with their number of occurrences in the file.
Then source code is split into the lines (statements) and the first for loop iterates through each line and removes the spaces in the statement of source code .
Then the lines are split into a list of words using split() method. The second for loop is used to iterate through each word in the list of words of the source code. Now each word is matched with the list of keywords of Python that is stored in keywords. If a word in the source code of the file is present in the keywords then that word is added to the dictionary and the count of that word is set to 1. If the word is already present in the dictionary. For example if there are 3 "import" keywords in the source code and if 1 of the import keywords is already in the dictionary. So when the second import keyword is found, then the count of that keyword is increased by 1 so that becomes 2.
Then the last loop is used to print each word of the Python that is a keyword along with its number of occurrences in the file.
The program and its output is attached in a screenshot. I have used this program as source code file.
Complete the function by filling in the missing parts. The color_translator function receives the name of a color, then prints its hexadecimal value. Currently, it only supports the three additive primary colors (red, green, blue), so it returns "unknown" for all other colors. m 1 - def color_translator(color): 2. if _== "red": 3 hex_color = "#ff0000" 4- elif == "green": 5 hex_color = "#00ff00" elif == "blue": hex_color = "#0000ff" in 0 hex_color = "unknown" return _ . 12 13 14 15 16 17 print(color_translator("blue")) # Should be #0000ff print(color_translator ("yellow")) # should be unknown print(color_translator("red")) # Should be #ff0000 print(color_translator ("black")) # should be unknown print(color_translator("green")) # Should be #00ff00 print(color translator("")) # should be unknown Run Reset
Answer:
The completed program is
def color_translator(color):
if color == "red":
hex_color = "#ff0000"
elif color == "green":
hex_color = "#00ff00"
elif color == "blue":
hex_color = "#0000ff"
else:
hex_color = "unknown"
return hex_color
Explanation:
Since the parameter in the above function is color,
This variable will serve as the name of a color and it'll be used in the conditional statements to check if the name of color is any of red, green and blue;
And that is why we have
if color == "red":
elif color == "green":
elif color == "blue":
The variable used to hold the color codes, hex_color, will be returned at the end of the function and that's why we have
return hex_color
When the program is tested with print(color_translator("blue")) and others, it prints the desired output
